The `cfcmsa` and `ctcmsa` instructions accept index of MSA control
register. The MIPS64 SIMD Architecture define eight MSA control
registers. But register index for `cfcmsa` and `ctcmsa` instructions
might be any number in 0..31 range. If the index is greater then 7,
`cfcmsa` writes zero to the destination registers and `ctcmsa` does
nothing [1].
