Simon Pilgrim f85ee9f8b4 [X86][SSE] Update raw mask shuffle decoders to handle UNDEF mask elts ... Matches the approach taken in the constant pool shuffle decoders, and uses an UndefElts mask instead of uint64_t(-1) raw mask values, which doesn't work safely for i32/i64 shuffle mask sizes (as the -1 value is legal). This allows us to remove the constant pool shuffle decoders from most of the getTargetShuffleMask variable shuffle cases (X86ISD::VPERMV3 will be handled in a future commit). llvm-svn: 345018		2018-10-23 11:33:38 +00:00
