c5fa9f413a Add support for sqrt, sqrtl, and sqrtf in TargetLibraryInfo. Disable 
(fptrunc (sqrt (fpext x))) -> (sqrtf x) transformation if -fno-builtin is 
specified.

5fade79478 MC/X86/COFF: Allow quotes in names when targeting MS/Windows, 
as MC is the only assembler we support.

This splits MS/Windows and GNU/Windows ASM infos into two seperate classes.
While there is currently only one difference, full MS C++ ABI support will
require many more.

5ce4e1a9d3 Fixed ObjectFile functions: 
- getSymbolOffset() renamed as getSymbolFileOffset()
- getSymbolFileOffset(), getSymbolAddress(), getRelocationAddress() returns same result for ELFObjectFile, MachOObjectFile and COFFObjectFile.
- added getRelocationOffset()
- fixed MachOObjectFile::getSymbolSize()
- fixed MachOObjectFile::getSymbolSection()
- fixed MachOObjectFile::getSymbolOffset() for symbols without section data.

d467aafd26 use llvm-config.h in public header 
The config.h file's macros collide with other projects that include
LLVM and shouldn't get exported.

9751c17d0d rename ENABLE_THREADS to LLVM_ENABLE_THREADS 
Now that it needs to be exported in a public header (Valgrind.h)
it should be prefixed to avoid collision with other projects.
Add it to llvm-config.h as well.

This'll require regenerating the configure script after this
commit, but I don't have the required autoconf version.

011a5bf0aa remove autoupgrade support for really old-style debug info intrinsics.

2709f65821 Break false dependencies before partial register updates. 
Two new TargetInstrInfo hooks lets the target tell ExecutionDepsFix
about instructions with partial register updates causing false unwanted
dependencies.

The ExecutionDepsFix pass will break the false dependencies if the
updated register was written in the previoius N instructions.

The small loop added to sse-domains.ll runs twice as fast with
dependency-breaking instructions inserted.

a0b2f7ca1d Refactor capture tracking (which already had a couple flags for whether returns 
and stores capture) to permit the caller to see each capture point and decide
whether to continue looking.

solve another devirtualization case, fixing PR8908!

53185e9016 Add support for tsan annotations (thread sanitizer, a valgrind-based tool). 
These annotations are disabled entirely when either ENABLE_THREADS is off, or
building a release build. When enabled, they add calls to functions with no
statements to ManagedStatic's getters.

Use these annotations to inform tsan that the race used inside ManagedStatic
initialization is actually benign. Thanks to Kostya Serebryany for helping
write this patch!

f89087744e Under the hood, MBPI is doing a linear scan of every successor every 
time it is queried to compute the probability of a single successor.
This makes computing the probability of every successor of a block in
sequence... really really slow. ;] This switches to a linear walk of the
successors rather than a quadratic one. One of several quadratic
behaviors slowing this pass down.

I'm not really thrilled with moving the sum code into the public
interface of MBPI, but I don't (at the moment) have ideas for a better
interface. My direction I'm thinking in for a better interface is to
have MBPI actually retain much more state and make *all* of these
queries cheap. That's a lot of work, and would require invasive changes.
Until then, this seems like the least bad (ie, least quadratic)
solution. Suggestions welcome.
