[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.
Fixes <rdar://problem/17608489>
