alpha.c (summarize_insn): Handle ASM_OPERANDS.

Browse Source 
* alpha.c (summarize_insn): Handle ASM_OPERANDS.  Don't recurse
        for SUBREG, just fall through.

        * alpha.c (alpha_handle_trap_shadows): Init sum.defd to zero.

        * alpha.md (attr trap): Make TRAP_YES non-zero for sanity's sake.
