[CSInfo][MIPS] Don't describe parameters loaded by sub- or super- register copy

Authored by ntesic on Jun 17 2020, 3:15 AM.



When describing parameter value loaded by a COPY instruction, consider case
where needed Reg value is a sub- or super- register of the COPY instruction's
destination register. Without this patch, compile process will crash with
the assertion "TargetInstrInfo::describeLoadedValue can't describe super- or
sub-regs for copy instructions".
