cmd/compile: remove unnecessary type conversions on s390x
Some rules insert MOVDreg ops to ensure that type changes are kept.
If there is no type change (or the input is constant) then the MOVDreg
can be omitted, allowing further optimization.
Reduces the size of the .text section in the asm tool by ~33KB.
