• [X86] Add another test case for the bug fixed in r229642. With the bug a vpsrldq was emitted instead of pslldq.

• [X86] Remove AVX512 pslldq/psrldq shift intrinsics. They aren't implemented yet and when they are they should be done with shuffles like SSE2 and AVX2.

• [X86] Remove AVX2 and SSE2 pslldq and psrldq intrinsics. We can represent them in IR with vector shuffles now. All their uses have been removed from clang in favor of shuffles.

• [X86] Remove the multiply by 8 that goes into the shift constant for X86ISD::VSHLDQ and X86ISD::VSRLDQ. This simplifies the pattern matching in isel and allows these nodes to become the patterns em…

• [X86] Add assembler predicates for the rest of the AVX512 feature flags. This makes the assembly matching consistent across all AVX512 instructions. Without this we were allowing some AVX512 instru…

• [X86] Add the remaining 11 possible exact ModRM formats. This makes their encodings linear which can then be used to simplify some other code.

• [X86] Improve parsing support AVX/SSE floating point compare instruction mnemonic aliases. They'll now print with the alias the parser received instead of converting to the explicit immediate form.

• [X86] Remove the remaining uses of memop from AVX and AVX2 instruction patterns. AVX and AVX2 can handle unaligned loads being folded so we can just use 'load'
