RISC-V: replace cbom instructions with an insn-def

Browse source

Using the cbom instructions directly in ALT_CMO_OP, requires toolchain
support for the instructions. Using an insn-def will allow for removal
of toolchain version checks in the build system & simplification of the
proposed [1] function-based CMO scheme.
