Cherry Mui d93ff73ae2 cmd/compile: don't elide extension for LoadReg to FP register on MIPS64
For an extension operation like MOWWreg, if the operand is already
extended, we optimize the second extension out. Usually a LoadReg
of a proper type would come already extended, as a MOVW/MOVWU etc.
instruction does. But for a LoadReg to a floating point register,
the instruction does not do the extension. So we cannot elide the
extension.

Fixes #50671.
