[llvm] AMDGPU: Delete seemingly dead s_fmaak_f32/s_fmamk_f32 folding code (PR #140580)

My interpretation of the comment is: some immediates are inlinable and some are not. So if we had an inlinable constant in the mandatory literal operand slot of the instruction, we want to commute the operands so the one that is inlinable is in the inlinable slot. 

As to whether it's for some reason dead code, I can't say.
