3a876ca187 Initial modifications to MCAssembler and TargetMachine for the MCJIT.

4924d5fb93 Custom lower the memory barrier instructions and add support 
for lowering without sse2.  Add a couple of new testcases.

Fixes a few libgomp tests and latent bugs.  Remove a few todos.

32f6aba7d8 Fix constant island pass's handling of tBR_JTr. The offset of the instruction does not have to be 4-byte aligned. Rather, it's the offset + 2 that must be aligned since the instruction expands into: 
mov     pc, r1
        .align  2
LJTI0_0_0:
        .long    LBB0_14

This fixes rdar://8213383. No test case since it's not possible to come up with a suitable small one.

5920e38cd2 Add more 256-bit forms for a bunch of regular AVX instructions 
Add 64-bit (GR64) versions of some instructions (which are not
described in their SSE forms, but are described in AVX)

c8342b43c4 Fixes win64. It was broken by a previous patch where I missed the !isWin64 
and then forced every register to be a vr128 on win64.

418c190d93 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.

e7ca21ab3b 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.

fc3ee085a0 Disallow null as a named metadata operand. 
Make MDNode::destroy private.
Fix the one thing that used MDNode::destroy, outside of MDNode itself.

One should never delete or destroy an MDNode explicitly. MDNodes
implicitly go away when there are no references to them (implementation
details aside).
