Remove PUSH_ARGS_REVERSED from the RTL expander.
gcc/
* calls.c (initialize_argument_information): Always treat
PUSH_ARGS_REVERSED as 1, simplify code accordingly.
(expand_call): Likewise.
(emit_library_call_calue_1): Likewise.
* expr.c (PUSH_ARGS_REVERSED): Do not define.
(emit_push_insn): Always treat PUSH_ARGS_REVERSED as 1, simplify
code accordingly.
