Elena Demikhovsky 29792e9a80 AVX-512: Added all forms of FP compare instructions for KNL and SKX. 
Added intrinsics for the instructions. CC parameter of the intrinsics was changed from i8 to i32 according to the spec.

Adam Nemet 5933c2f824 [X86] AVX512: Add disassembler support for compressed displacement 
There are two parts here.  First is to modify tablegen to adjust the encoding
type ENCODING_RM with the scaling factor.

The second is to use the new encoding types to compute the correct
displacement in the decoder.

Adam Nemet 8ae70506ea [Disasm][AVX512] Implement decoding of top bit for non-destructive reg fields 
V' bit in the P2 byte of the EVEX prefix provides the top bit of the NDD and
NDS register fields.  This was simply not used in the decoder until now.

Fixes <rdar://problem/17402661>
