Don't use inline assembly in 64-bit Visual Studio. Unfortunately, this means that cpuid leaf 7 can't be queried on versions of Visual Studio earlier than VS 2008 SP1. Fixes PR11147.

Add metadata to the canonicalize_branch InstCombine test, and check that
it is tranformed correctly.

movl 0(%rax), 0(%edx)

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

Add X86 BEXTR instruction. This instruction uses VEX.vvvv to encode Operand 3 instead of Operand 2 so needs special casing in the disassembler and code emitter. Ultimately, should pass this information from tablegen

Add X86 feature detection support for BMI instructions. Added new cpuid function for accessing leafs with sub leafs specified in ECX. Also added code to keep track of the max cpuid level supported in both basic and extended leaves and qualified the existing cpuid calls and the new call to leaf 7.

Add support for X86 blsr, blsmsk, and blsi instructions. Required extra work because these are the first VEX encoded instructions to use the reg field as an opcode extension.

Based on Horspool's simplified version of Boyer-Moore. We use a constant-sized table of
uint8_ts to keep cache thrashing low, needles bigger than 255 bytes are uncommon anyways.

The worst case is still O(n*m) but we do a lot better on the average case now.

Just because we're dealing with a GEP doesn't mean we can assert the
SCEV has a pointer type. The fix is simply to ignore the SCEV pointer
type, which we really didn't need.

I rewrote the algorithm a while back so it doesn't require map lookup,
but neglected to change the data structure. This was caught by
llvm-gcc self host, not because there's anything special about
llvm-gcc, but because it is the only test for nondeterminism we
currently have. Unit tests don't work well for everything; we should
always try to have a nondeterminism stress test running.

Fixes PR11133: llvm-gcc self host .o mismatch after enable-iv-rewrite=false
