Implement proper handling for pcmpistri/pcmpestri intrinsics. Requires custom handling in DAGISelToDAG due to limitations in TableGen's implicit def handling. Fixes PR11305.

Use XOP vpcom intrinsics in patterns instead of a target specific SDNode type. Remove the custom lowering code that selected the SDNode type.

Change type profile for vpermv back to using operand type for the mask argument to match intrinsic behavior. Add a bitcast to the lowering code to convert mask from v8i32 to v8f32 for vpermps.

Original message:
Modify the code that lowers shuffles to blends from using blendvXX to vblendXX.
blendV uses a register for the selection while Vblend uses an immediate.
On sandybridge they still have the same latency and execute on the same execution ports.

Original commit message from r147481:
DAGCombine for transforming 128->256 casts into a vmovaps, rather
then a vxorps + vinsertf128 pair if the original vector came from a load.

Fix:
Unaligned loads need to generate a vmovups.

Emacs-tag and some comment fix for all ARM, CellSPU, Hexagon, MBlaze, MSP430, PPC, PTX, Sparc, X86, XCore.

Move old movl vector_shuffle patterns. Not needed anymore since vector_shuffles shouldn't reach isel.

It caused 3 failures on pre-penryn and non-x86(generic) hosts.

Remove some patterns for matching vector_shuffle instructions since vector_shuffles should be custom lowered before isel.

llvm-svn: 150299

Add target specific node for PMULUDQ. Change patterns to use it and custom lower intrinsics to it. Use it instead of intrinsic to handle 64-bit vector multiplies.

llvm-svn: 149807

Special handling was added for v4i32 -> v4i64 and v8i16 -> v8i32
extensions.

llvm-svn: 149600

Move some XOP patterns into instruction definition. Replae VPCMOV intrinsic patterns with custom lowering to a target specific nodes.

llvm-svn: 149216

Custom lower PSIGN and PSHUFB intrinsics to their corresponding target specific nodes so we can remove the isel patterns.

llvm-svn: 148933

Add comments near load pattern fragments indicating that all integer vector loads are promoted to v2i64 or v4i64 so that no one tries to reintroduce pattern fragments for other types.

llvm-svn: 148771

Remove pattern fragments for v32i8, v16i16, v8i32, v16i8, v8i16, and v4i32 loads. All integer vector loads are promoted to v2i64 or v4i64 so these pattern fragments can never match. Fix or remove patterns that used these fragments.

Merge PCMPEQB/PCMPEQW/PCMPEQD/PCMPEQQ and PCMPGTB/PCMPGTW/PCMPGTD/PCMPGTQ X86 ISD node types into only two node types. Simplifying opcode selection and pattern matching.

llvm-svn: 148667

Add target specific ISD node types for SSE/AVX vector shuffle instructions and change all the code that used to create intrinsic nodes to create the new nodes instead.

Remove some remants of the old palign pattern fragment that were still hanging around. Also remove a cast from inside getShuffleVPERM2X128Immediate and getShuffleVPERMILPImmediate since the only caller already had done the cast.

Merge decoding of VPERMILPD and VPERMILPS shuffle masks. Merge X86ISD node type for VPERMILPD/PS. Add instruction selection support for VINSERTI128/VEXTRACTI128.

llvm-svn: 145483

Add X86 instruction selection for VPERM2I128 when AVX2 is enabled. Merge VPERMILPS/VPERMILPD detection since they are pretty similar.
