Summary:
The validity of ABI/CPU pairs is no longer checked on the fly but is
instead checked after initialization. As a result, invalid CPU/ABI pairs
can be reported as being known but invalid instead of being unknown. For
example, we now emit:
error: ABI 'n32' is not supported on CPU 'mips32r2'
instead of:
error: unknown target ABI 'n64'

Summary:
There are no llvm backend tests* for EABI and no EABI buildbots. There were only
three clang tests, all of which checked that -mabi=eabi was passed to the
assembler.
*There is a single backend test that specifies EABI but it actually tests MIPS16.

This unifies mips/mipsel and mips64/mips64el into a single class so that we can
later support O32 on mips64/mips64el and N32/N64 on mips/mipsel (when an

Summary:
Following patch D19265 which enable software floating point support in the Sparc backend, this patch enables the option to be enabled in the front-end using the -msoft-float option.
The user should ensure a library (such as the builtins from Compiler-RT) that includes the software floating point routines is provided.

The `FreeBSDTargetInfo` class has always set the `__FreeBSD_cc_version`
predefined macro to a rather static value, calculated from the major OS
version.
In the FreeBSD base system, we will start incrementing the value of this
macro whenever we make any signifant change to clang, so we need a way
to configure the macro's value at build time.
Use `FREEBSD_CC_VERSION` for this, which we can define in the FreeBSD
build system using either the `-D` command line option, or an include
file. Stock builds will keep the earlier value.

Summary:
MONITORX/MWAITX instructions provide similar capability to the MONITOR/MWAIT
pair while adding a timer function, such that another termination of the MWAITX
instruction occurs when the timer expires. The presence of the MONITORX and
MWAITX instructions is indicated by CPUID 8000_0001, ECX, bit 29.
The MONITORX and MWAITX instructions are intercepted by the same bits that
intercept MONITOR and MWAIT. MONITORX instruction establishes a range to be
monitored. MWAITX instruction causes the processor to stop instruction
execution and enter an implementation-dependent optimized state until
occurrence of a class of events.
Opcode of MONITORX instruction is "0F 01 FA". Opcode of MWAITX instruction is
"0F 01 FB". These opcode information is used in adding tests for the
disassembler.
These instructions are enabled for AMD's bdver4 architecture.

Reapply r269100 and r269270, reverted due to
https://llvm.org/bugs/show_bug.cgi?id=27725. Isolate the testcase that
corresponds to the new feature side of this commit and skip it on
windows hosts until we find why it does not work on these platforms.
Original commit message:
The way we currently build the internal VFS overlay representation leads
to inefficient path search and might yield wrong answers when asked for
recursive or regular directory iteration.
Currently, when reading an YAML file, each YAML root entry is placed
inside a new root in the filesystem overlay. In the crash reproducer, a
simple "@import Foundation" currently maps to 43 roots, and when looking
up paths, we traverse a directory tree for each of these different
roots, until we find a match (or don't). This has two consequences:
- It's slow.
- Directory iteration gives incomplete results since it only return
results within one root - since contents of the same directory can be
declared inside different roots, the result isn't accurate.
This is in part fault of the way we currently write out the YAML file
when emitting the crash reproducer - we could generate only one root and
that would make it fast and correct again. However, we should not rely
on how the client writes the YAML, but provide a good internal
representation regardless.
Build a proper virtual directory tree out of the YAML representation,
allowing faster search and proper iteration. Besides the crash
reproducer, this potentially benefits other VFS clients.

clang support on Haiku is lagging a bit, and missing on x86_64.
This patch updates support for x86 and add support for x86_64. It should
apply directly to trunk and it's harmless in the sense that it only

This patch corresponds to reviews:
http://reviews.llvm.org/D15120http://reviews.llvm.org/D19125
It adds support for the __float128 keyword, literals and target feature to
enable it. Based on the latter of the two aforementioned reviews, this feature
is enabled on Linux on i386/X86 as well as SystemZ.
This is also the second attempt in commiting this feature. The first attempt
did not enable it on required platforms which caused failures when compiling
type_traits with -std=gnu++11.
If you see failures with compiling this header on your platform after this
commit, it is likely that your platform needs to have this feature enabled.

This code implements builtin_setjmp and builtin_longjmp exception handling intrinsics for 32-bit Sparc back-ends.
The code started as a mash-up of the PowerPC and X86 versions, although there are sufficient differences to both that had to be made for Sparc handling.
Note: I have manual tests running. I'll work on a unit test and add that to the rest of this diff in the next day.
Also, this implementation is only for 32-bit Sparc. I haven't focussed on a 64-bit version, although I have left the code in a prepared state for implementing this, including detecting pointer size and comments indicating where I suspect there may be differences.
