06cb680779 Collapse X86ISD node types for PUNPCKH*, PUNPCKL*, UNPCKLP*, and UNPCKHP* to not be type specific. Now we just have integer high and low and floating point high and low. Pattern matching will choose the correct instruction based on the vector type.

1b9b377975 This patch contains support for encoding FMA4 instructions and 
tablegen patterns for scalar FMA4 operations and intrinsic. Also
add tests for vfmaddsd.

705f2431a0 Remove 256-bit specific node types for UNPCKHPS/D and instead use the 128-bit versions and let the operand type disinquish. Also fix the load form of the v8i32 patterns for these to realize that the load would be promoted to v4i64.

f238f50aaf X86: Use btq for bit tests if the immediate can't be encoded in 32 bits. 
Before:
	movabsq	$4294967296, %rax       ## encoding: [0x48,0xb8,0x00,0x00,0x00,0x00,0x01,0x00,0x00,0x00]
	testq	%rax, %rdi              ## encoding: [0x48,0x85,0xf8]
	jne	LBB0_2                  ## encoding: [0x75,A]

After:
	btq	$32, %rdi               ## encoding: [0x48,0x0f,0xba,0xe7,0x20]
	jb	LBB0_2                  ## encoding: [0x72,A]

btq is usually slower than testq because it doesn't fuse with the jump, but here we're better off
saving one register and a giant movabsq.

52a35a89e6 I added several lines in X86 code generator that allow to choose 
VSHUFPS/VSHUFPD instructions while lowering VECTOR_SHUFFLE node. I check a commuted VSHUFP mask.

The patch was reviewed by Bruno.

7f5e43f61d Fix PR11422. 
This was a bug in keeping track of the available domains when merging
domain values.

The wrong domain mask caused ExecutionDepsFix to try to move VANDPSYrr
to the integer domain which is only available in AVX2.

Also add an assertion to catch future attempts at emitting AVX2
instructions.

c2ecf3efbf 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.
