b3f7e28cb6 Remove modifierType/Base from X86 disassembler tables as they are no longer used. Removes ~11.5K from static tables.

9d2e15270b Remove need for MODIFIER_OPCODE in the disassembler tables. AddRegFrms are really more like OrRegFrm so we don't need a difference since we can just mask bits.

4454a2fa93 Second attempt at Removing special form of AddRegFrm used by FP instructions. These instructions can be handled by MRMXr instead.

24d8bb6edd [x86] Rename In32BitMode predicate to Not64BitMode 
That's what it actually means, and with 16-bit support it's going to be
a little more relevant since in a few corner cases we may actually want
to distinguish between 16-bit and 32-bit mode (for example the bare 'push'
aliases to pushw/pushl etc.)

b43ccbc3f7 AVX-512: Added legal type MVT::i1 and VK1 register for it. 
Added scalar compare VCMPSS, VCMPSD.
Implemented LowerSELECT for scalar FP operations.
I replaced FSETCCss, FSETCCsd with one node type FSETCCs.
Node extract_vector_elt(v16i1/v8i1, idx) returns an element of type i1.

aa1a4d51f0 Remove some instructions that existed to provide aliases to the assembler. Can be done with InstAlias instead. Unfortunately, this was causing printer to use 'vmovq' or 'vmovd' based on what was parsed. To cleanup the inconsistencies convert all 'vmovd' with 64-bit registers to 'vmovq', but provide an alias so that 'vmovd' will still parse.

aa267b3e82 Add support for encoding the HLE XACQUIRE and XRELEASE prefixes. 
For decoding, keep the current behavior of always decoding these as their REP
versions. In the future, this could be improved to recognize the cases where
these behave as XACQUIRE and XRELEASE and decode them as such.

0c823ae0ed Add intrinsics, code gen, assembler and disassembler support for the SSE4a extrq and insertq instructions.

and two immediates.
