Instead of doing a binary search over the whole diagnostic table (which weighs
a whopping 48k on x86_64), use the existing enums to compute the index in the
table. This avoids loading any unneeded data from the table and avoids littering
CPU caches with it. This code is in a hot path for code with many diagnostics.

1% speedup on -fsyntax-only gcc.c, which emits a lot of warnings.

is not needed.

Doing just 'stat' is faster than 'open/fstat/close'.
This has the effect of cutting down system time for validating the input files of a PCH.

Linux too, as I think we inherited it from there.  The ABI spec says 128-bit,
although I think SGI's compiler on IRIX may be the only thing ever to support
this.

with -Werror.  Previously, compiling with -Werror would emit only the first
warning in a compilation unit, because clang assumes that once an error occurs,
further analysis is unlikely to return valid results.  However, warnings that
have been upgraded to errors should not be treated as "errors" in this sense.

uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

The 'a', 'c', and 'd' constraints on i386 mean a 32-bit register. We cannot
place a 64-bit value into the 32-bit register. Error out instead of causing the
compiler to spew general badness.

- New options '-mrtm'/'-mno-rtm' are added to enable/disable RTM feature
- Builtin macro '__RTM__' is defined if RTM feature is enabled
- RTM intrinsic header is added and introduces 3 new intrinsics, namely
  '_xbegin', '_xend', and '_xabort'.
- 3 new builtins are added to keep compatible with gcc, namely
  '__builtin_ia32_xbegin', '__builtin_ia32_xend', and '__builtin_ia32_xabort'.
- Test cases for pre-defined macro and new intrinsic codegen are added.

Haiku does not support this (yet). Leaving it set to true leads to
configure scripts detecting __thread being available and Clang emitting
code for it, resulting in binaries the runtime_loader will refuse to
load.

 - The whole {File,Source}Manager is built around wanting to pre-determine the

   we do STDIN, where we just replace the main file contents upfront.

ELF subtarget.

The existing description string is moved from PPC64TargetInfo to its
DarwinTargetInfo subclass, to avoid any changes to the Darwin ABI.
PPC64TargetInfo now has two possible description strings: one for FreeBSD,
which requires 8-byte alignment, and a default string that requires
16-byte alignment.

I've added a test for PPC64 Linux to verify the 16-byte alignment.  If
somebody wants to add a separate test for FreeBSD, that would be great.

Note that there is a companion patch to update the alignment information
in LLVM, which I am committing now as well.
