[VE] Support convert instructions in MC layer

Summary:
Add CVTSQ/CVTDQ/CVTQD/CVTQS instructions.  Add regression tests for
them and other convert instructions of asmparser, mccodeemitter, and
disassembler.  In order to add those instructions, support RD operands
in asmparser, mccodeemitter, and disassembler.
