emit-rtl.c (last_call_insn, [...]): New functions.
* emit-rtl.c (last_call_insn, add_function_usage_to): New functions.
* rtl.h (last_call_insn, add_function_usage_to): New prototypes.
* builtins.c (expand_builtin_apply): Use the new emit-rtl functions.
* calls.c (emit_call_1): Likewise.
(expand_call): For calls initializing constant memory, replace
emission of standalone mem /u clobber with function usage entry.
* expr.c (emit_block_move_via_libcall): Likewise.
* cse.c (count_reg_usage, case EXPR_LIST): New case.
* flow.c (propagate_one_insn): Pass entire operand of
CALL_INSN_FUNCTION_USAGE to mark_used_regs.
* integrate.c (try_constants): For CALL_INSNs, substitute constants
within the FUNCTION_USAGE also.
* loop.c (prescan_loop): Note clobbers of const mem mentioned in
FUNCTION_USAGE lists.
* reload1.c (replace_pseudos_in): Renamed.
(reload): Use it for clobbers surviving until the end of the reload.
