It doesn't like the implicit conversion from T[] to ArrayRef<T>

1f0f5b5b9e Convert option tables to ArrayRefs.
This change is very mechanical.  All it does is change the
signature of `Options::GetDefinitions()` and `OptionGroup::
GetDefinitions()` to return an `ArrayRef<OptionDefinition>`
instead of a `const OptionDefinition *`.  In the case of the
former, it deletes the sentinel entry from every table, and
in the case of the latter, it removes the `GetNumDefinitions()`
method from the interface.  These are no longer necessary as
`ArrayRef` carries its own length.

In the former case, iteration was done by using a sentinel
entry, so there was no knowledge of length.  Because of this
the individual option tables were allowed to be defined below
the corresponding class (after all, only a pointer was needed).
Now, however, the length must be known at compile time to
construct the `ArrayRef`, and as a result it is necessary to
move every option table before its corresponding class.  This
results in this CL looking very big, but in terms of substance
there is not much here.

7ffdb1556b fix DarwinLog no-info/no-debug case
This started failing recently:
TestDarwinLogSourceDebug.py

It looks like the behavior of specifying the OS_ACTIVITY_MODE
env var with no value used to work for no-info/no-debug content.
That doesn't appear to be the case now.  Switch to specifying
the proper value ('default') when no info-level and no debug-level
content is expected.

d3199f5ed2 [CMake] Initial support for LLDB.framework
Summary:
This patch adds a CMake option LLDB_BUILD_FRAMEWORK, which builds libLLDB as a macOS framework instead of as a *nix shared library.

With this patch any LLDB executable that has the INCLUDE_IN_FRAMEWORK option set will be built into the Framework's resources directory, and a symlink to the exeuctable will be placed under the build directory's bin folder. Creating the symlinks allows users to run commands from the build directory without altering the workflow.

The framework generated by this patch passes the LLDB test suite, but has not been tested beyond that. It is not expected to be fully ready to ship, but it is a first step.

With this patch binaries that are placed inside the framework aren't being properly installed. Fixing that would increase the patch size significantly, so I'd like to do that in a follow-up.

9666ba7526 add stop column highlighting support
This change introduces optional marking of the column within a source
line where a thread is stopped.  This marking will show up when the
source code for a thread stop is displayed, when the debug info
knows the column information, and if the optional column marking is
enabled.

There are two separate methods for handling the marking of the stop
column:

* via ANSI terminal codes, which are added inline to the source line
  display.  The default ANSI mark-up is to underline the column.

* via a pure text-based caret that is added in the appropriate column
  in a newly-inserted blank line underneath the source line in
  question.

There are some new options that control how this all works.

* settings set stop-show-column

  This takes one of 4 values:

  * ansi-or-caret: use the ANSI terminal code mechanism if LLDB
    is running with color enabled; if not, use the caret-based,
    pure text method (see the "caret" mode below).

  * ansi: only use the ANSI terminal code mechanism to highlight
    the stop line.  If LLDB is running with color disabled, no
    stop column marking will occur.

  * caret: only use the pure text caret method, which introduces
    a newly-inserted line underneath the current line, where
    the only character in the new line is a caret that highlights
    the stop column in question.

  * none: no stop column marking will be attempted.

* settings set stop-show-column-ansi-prefix

  This is a text format that indicates the ANSI formatting
  code to insert into the stream immediately preceding the
  column where the stop column character will be marked up.
  It defaults to ${ansi.underline}; however, it can contain
  any valid LLDB format codes, e.g.

      ${ansi.fg.red}${ansi.bold}${ansi.underline}

* settings set stop-show-column-ansi-suffix

  This is the text format that specifies the ANSI terminal
  codes to end the markup that was started with the prefix
  described above.  It defaults to: ${ansi.normal}.  This
  should be sufficient for the common cases.

Significant leg-work was done by Adrian Prantl.  (Thanks, Adrian!)

2552acd945 Fix failing regex tests.
r282079 converted the regular expression interface to accept
and return StringRefs instead of char pointers.  In one case
a null pointer check was converted to an empty string check,
but this was an incorrect conversion because an empty string
is a valid regular expression.  Removing this check should
fix the test failures.

58db5bb20e Refactor NativeRegisterContextLinux_x86_64 code.
This patch refactors the way the XState type is checked and, in order to
simplify the code, it removes the usage of the 'cpuid' instruction: just checking
if the ptrace calls done throuhg ReadFPR is enough to verify both if there is
HW support and if there is kernel support. Also the XCR0 bits are enough to check if
there is both HW and kernel support for AVX and MPX.

ecbb0bb169 Fix more functions in Args to use StringRef.
This patch also marks the const char* versions as =delete to prevent
their use.  This has the potential to cause build breakages on some
platforms which I can't compile.  I have tested on Windows, Linux,
and OSX.  Best practices for fixing broken callsites are outlined in
Args.h in a comment above the deleted function declarations.

Eventually we can remove these =delete declarations, but for now they
are important to make sure that all implicit conversions from
const char * are manually audited to make sure that they do not invoke a
conversion from nullptr.

7f193d6903 [RenderScript] Support tracking and dumping reduction kernels
Initial implementation of support for tracking
[RenderScript Reductions](https://developer.android.com/guide/topics/renderscript/compute.html#reduction-in-depth)

With this patch, `language renderscript module dump` properly lists reductions
that are part of loaded RenderScript modules as well the the consituent
functions and their roles, within the reduction.

This support required new tracking mechanisms for the `#pragma(reduce)`
mechanism, and extension of `RSModuleDescriptor::ParseRSInfo` to support
the metadata output by `bcc`. This work was also an opportunity to
refactor/improve parse code:

- `RSModuleDescriptor::ParseExportReduceCount` now has a complete
  implementation and the debugger can correctly track reductions on
  receipt of a module hook.
- `RSModuleDescriptor::Dump` now dumps Reductions as well as `ForEach`
  kernels. Also, fixed indentation of the output, and made indentation
  groupings in the source clearer.
- `RSModuleDescriptor::ParseRSInfo` now returns true if the `".rs.info"`
  packet has nonzero linecount, rather than rejecting RenderScripts that
  don't contain kernels (an unlikely situation, but possibly valid). This
  was changed because scripts that only contained reductions were not
  being tracked in `RenderScriptRuntime::LoadModule`.
- Refactor `RSModuleInfo::ParseRSInfo` and add reduction spec parser stub
 - Prepared ParseRSInfo to more easily be able to add new parser types
 - Use llvm::StringRef and llvm::StringMap helpers to make the parsing code cleaner
 - factor out forEachCount, globalVarCount, and pragmaCount parsing block to their own methods
 - Add ExportReduceCount Parser
 - Use `llvm::StringRef` in `RSKernelDescriptor` constructor
 - removed now superfluous `MAXLINE` macros as we've switched from `const
   char *` to `llvm::StringRef`

f6607454d4 Convert ArchSpec::ParseMachOCPUDashSubtypeTriple to use StringRef.
This makes the code easier to grok, and since this is a very low
level function it also is very helpful to have this take a StringRef
since it means anyone higher up the chain who has a StringRef would
have to first convert it to a null-terminated string.  This way it
can work equally well with StringRefs or const char*'s, which will
enable the conversion of higher up functions to StringRef.

Tested on Windows, Linux, and OSX and saw no regressions.
