arch-riscv: Add support for compressed extension RV64C

This patch adds compatibility with the 64-bit compressed extension to
the RISC-V ISA, RV64C.  Current versions of the toolchain may use
compressed instructions in glibc by default, which can only be
overridden by recompiling the entire toolchain (simply adding
"-march=rv64g" or "-march=rv64imafd" when compiling a binary is not
sufficient to use uncompressed instructions in glibc functions in the
binary).

[Update diassembly generation for new RegId type.]
[Rebase onto master.]
