fb583a9842 Add remaining AVX instructions (most of them dealing with GR64 destinations. This complete the assembler support for the general AVX ISA. But we still miss instructions from FMA3 and CLMUL specific feature flags, which are now the next step

456fdaf0ce instead of migrating it to the MC instruction encoder, just 
rip out the implementation of X86InstrInfo::GetInstSizeInBytes.
The code being ripped out just implemented a copy and hacked up
version of the (old) instruction encoder, and is buggy and 
terrible in other ways.  Since "GetInstSizeInBytes" is really 
only there to support the JIT's "NeedsExactSize" hook (which
noone is using), just rip out the code.  I will rip out the
NeedsExactSize hook next.

This resolves rdar://7617809 - switch X86InstrInfo::GetInstSizeInBytes to use X86MCCodeEmitter

908bafe6fa add some rough support for making mcinst lowering work without an 
asmprinter or mangler around.  This is option #B for killing off 
X86InstrInfo::GetInstSizeInBytes.  Option #A (killing 
"needsexactsize") was sent for consideration to llvmdev.

c8ea673bc0 Fix a couple issues with Win64 ABI 
1) all registers were spilled as xmm, regardless of actual size
2) win64 abi doesn't do the varargs-size-in-%al thing

Still to look into:

xmm6-15 are marked as clobbered by call instructions on win64 even though they aren't.

aef40351f6 fix a layering problem by moving the x86 implementation 
of AsmPrinter and InstLowering into libx86 and out of the
asmprinter subdirectory.  Now X86/AsmPrinter just depends on
MC stuff, not all of codegen and LLVM IR.

   the ambiguity between 'jmpl' and 'jmpq'.
