Kit Barton f4ce2f3a9e Enable shrink wrapping for PPC64 
Re-enable shrink wrapping for PPC64 Little Endian.

One minor modification to PPCFrameLowering::findScratchRegister was necessary to handle fall-thru blocks (blocks with no terminator) correctly.

Tested with all LLVM test, clang tests, and the self-hosting build, with no problems found.

Daniel Sanders d32db286a0 [mips][ias] Removed MSA instructions from base architecture valid-xfail.s's. 
valid-xfail.s is for instructions that should be valid in the given ISA but

Craig Topper aad5f11e5f [AVX512] The vpermi2 instructions require an integer vector for the index vector. This is reflected correctly in the intrinsics, but was not refelected in the isel patterns. 
For the floating point types, this requires adding a bitcast to the index vector when its passed through to the output.

Davide Italiano b8b7133c94 [SimplifyLibCalls] Tranform log(pow(x, y)) -> y*log(x). 
This one is enabled only under -ffast-math. There are cases where the
difference between the value computed and the correct value is huge
even for ffast-math, e.g. as Steven pointed out:

x = -1, y = -4
log(pow(-1), 4) = 0
4*log(-1) = NaN

I checked what GCC does and apparently they do the same optimization
(which result in the dramatic difference). Future work might try to
make this (slightly) less worse.

Diego Novillo 7ff0a174d1 SamplePGO - Do not use std::to_string in diagnostics. 
This fixes buildbots in systems that std::to_string is not present. It
also tidies the output of the diagnostic to render doubles a bit better
(thanks Ben Kramer for help with string streams and format).

Xinliang David Li b75544a6df [PGO] Move value profile format related structures and APIs to common file 
This is the last step to enable profile runtime to share the same value prof
data format and reader/writer code with llvm host tools. The VP related 
data structures are moved to a section in InstrProfData.inc enabled with macro
INSTR_PROF_VALUE_PROF_DATA, and common API implementations are enabled with
INSTR_PROF_COMMON_API_IMPL. There should be no functional change.
