[PATCH] D133012: [AMDGPU] Add subtarget feature for MAD_U64/I64 bug on GFX11

Following an offline discussion I've looked into adding a subtarget feature for bug for V_MAD_U64_U32 and V_MAD_I64_I32. Since VOPReal is tied with VOPPseudo I don't see a nice way of having both options for gfx11 without also having 2 real versions. 
If we don't care about having an option to disable this bug on gfx11 then we can just eliminate the other Real.
