But right now register_operand still accepts `(SUBREG (MEM...))`
before reload ...
So basically there is a check against register_operand to then
reg_or_subregno is called
but since register_operand allows `(SUBREG (MEM())` but
reg_or_subregno asserts on only having `REG` or `SUBREG(REG)`, things
go downhill.
What a mess. I really wish `(SUBREG (MEM...))` handling would go away ...
Thanks,

OK I guess change register_operand into REG_P should fix those ICEs.
I will have a try and send a patch.
Thanks.
