RISC-V: vectorised memory operations

Dec. 11, 2023, 9:47 a.m. UTC
This patchset permits generation of inlined vectorised code for movmem,
setmem and cmpmem, if and only if the operation size is
at least one and at most eight vector registers' worth of data.
Further vectorisation rapidly becomes debatable due to code size concerns;
however, for these simple cases we do have an unambiguous performance win
without sacrificing too much code size compared to a libc call.
