Add input_modes parameter to TARGET_MD_ASM_ADJUST hook
If TARGET_MD_ASM_ADJUST changes a mode of an input operand (which
should be ok as long as the hook itself as well as after_md_seq make up
for it), input_mode will contain stale information.
It might be tempting to fix this by removing input_mode altogether and
just using GET_MODE (), but this will not work correctly with constants.
So add input_modes parameter and document that it should be updated
whenever inputs parameter is updated.
