output_add_clobbers emits code to add:

   (clobber (scratch:M))

and/or:

   (clobber (reg:M R))

expressions to the end of a PARALLEL.  At the moment, it does this
using the general gen_exp function.  That makes sense with the code
in its current form, but with later patches it's more convenient to
handle the two cases directly.

This also avoids having to pass an md_rtx_info that is unrelated
to the clobber expressions.

gcc/
        * genemit.cc (clobber_pat::code): Delete.
        (maybe_queue_insn): Don't set clobber_pat::code.
        (output_add_clobbers): Remove info argument and output the two
        REG and SCRATCH cases directly.
        (main): Update call accordingly.

OK
