  Log Message:
  -----------
  [RISCV] Move FRM parsing in the assembler to a custom operand parser.

Previously we parsed it as a symbol, and then accessed the name.
This works, but seems like an unusual way to do it.

This adds a custom parser that looks for an Identifier token containing
one of the valid FRM strings.
