Aleksandar Beserminji 4c4c0377ca [mips] Optimize shifts for types larger than GPR size (mips2/mips3) ...

With this patch, shifts are lowered to optimal number of instructions
necessary to shift types larger than the general purpose register size.

This resolves PR/32293.

Thanks to Kyle Butt for reporting the issue!
