36787939b2 Add definitions of instructions which move values between 64-bit integer 
registers and 64-bit HI and LO registers. Fix encoding of the 32-bit versions
of the instructions.

e1b4a1a07e Fix disassembler handling of CRC32 which is an odd instruction that uses 0xf2 as an opcode extension and allows the opsize prefix. This necessitated adding IC_XD_OPSIZE and IC_64BIT_XD_OPSIZE contexts. Unfortunately, this increases the size of the disassembler tables. Fixes PR10702.

c8e2bb68bb Store sub-class lists as a bit vector. 
This uses less memory and it reduces the complexity of sub-class
operations:

- hasSubClassEq() and friends become O(1) instead of O(N).

- getCommonSubClass() becomes O(N) instead of O(N^2).

In the future, TableGen will infer register classes.  This makes it
cheap to add them.

4ebbf7b8a8 ARM fix encoding of VMOV.f32 and VMOV.f64 immediates. 
Encode the immediate into its 8-bit form as part of isel rather than later,
which simplifies things for mapping the encoding bits, allows the removal
of the custom disassembler decoding hook, makes the operand printer trivial,
and prepares things more cleanly for handling these in the asm parser.
