95dd80c2e8 [analyzer] Avoid querying this-pointers for static-methods.
Summary:
The loop-widening code processes c++ methods looking for `this` pointers.  In
the case of static methods (which do not have `this` pointers), an assertion
was triggering.   This patch avoids trying to process `this` pointers for
static methods, and thus avoids triggering the assertion .

381e9d2386 [Coverage] Ignore 'unused' functions with non-zero execution counts
Frontends emit 'unused' coverage mapping records for functions which are
provably unused in a TU. These unused records contain a single counter
with CounterKind::Zero. However, a function may be unused in one TU and
used in another. When this happens, prefer the records with a full set
of counters instead of arbitrarily picking the first loaded record.

There is no impact on the single-TU case. In the multiple-TU case, this
resolves issues causing a function to appear unused when it's not.

Testing: check-{llvm,clang,compiler-rt}

7b2c98ab59 AMDGPU: Remove broken i16 ternary patterns
Fixup test to check for GCN prefix
These patterns always zero extend the result even though it might need sign extension.
This has been broken since the addition of i16 support.
It has popped up in mad_sat(char) test since min(max()) combination is turned into v_med3, resulting in the following (incorrect) sequence:
        v_mad_i16 v2, v10, v9, v11

7aa4ed9b5f If a function starts with line number 0, don't try to check if a breakpoint crossed function boundaries.
clang doesn't use line number 0 (to mean artifically generated code) very often, but swift does it
quite often.  We were rejecting all by line breakpoints in functions that started at line 0.  But that's
a special marker so we can just not do this test in that case.

8efc95ac2f [lit, python3] Update lit error logging to work correctly in python3 and other test fixes
Summary:
In Python2 'unicode' is a distinct type from 'str', but in Python3 'unicode' does not exist and instead all 'str' objects are Unicode string. This change updates the logic in the test logging for lit to correctly process each of the types, and more importantly, to not just fail in Python3.

This change also reverses the use of quotes in several of the cfg files. By using '""' we are guaranteeing that the resulting path will work correctly on Windows while "''" only works correctly sometimes. This also fixes one of the failing tests.

875f6dae86 Update msbuild integration warnings: Don't warn on /Zi and /X
We do need to map /Zi to /Z7 explicitly for msbuild as explained in this file,
but since /Zi is passed by default and since things transparently work fine
with it mapped to /Z7, we shouldn't produce effectively inactionable noise for
it.

Also don't warn on /X since clang-cl supports that (since r326357; the risk of
duplicating a bunch of clang-cl driver logic here).

7add582032 [Sema] Fix for crash on conditional operation with address_space pointer
Compiling the following causes clang to crash

```
char *cmp(__attribute__((address_space(1))) char *x, __attribute__((address_space(2))) char *y) {
  return x < y ? x : y;
}
```

with the message: "wrong cast for pointers in different address
spaces(must be an address space cast)!"

This is because during IR emission, the source and dest type for a
bitcast should not have differing address spaces.

This fix prints an error since the code shouldn't compile in the first place.

f4f5b7eea3 lld-link: Take /SUBSYSTEM into account for automatic /ENTRY detection.
If /subsystem:windows is passed, link.exe only looks for WinMain and wWinMain,
and if /subsystem:console is passed it only looks for main and wmain. lld-link
used to look for all 4 in both cases. This patch makes lld-link match
link.exe's behavior.

This requires that the subsystem is known by the time findDefaultEntry() gets
called. findDefaultEntry() is called before the main link loop, so that the
loop can mark the entry point as undefined. That means inferSubsystem() has to
be called above the main loop as well. This in turn means /subsystem: from
.drectve sections only has an effect on entry point inference for obj files
passed to lld-link directly (and not in obj files found later in .lib files).
link.exe seems to ignore /subsystem: for obj files from lib files completely
(while in lld it's ignored only for entry point detection but it still
overrides /subsystem: flags passed on the command line for the value that gets
written in the output file).

Also, if the subsytem isn't needed (e.g. when only writing a /def: lib file and
not writing a coff file), link.exe doesn't complain if the subsystem isn't
known, so both subsystem and entry point handling should be below the early
return lld has for that case.

Fixes PR36523.
