* rtlanal.c (operand_preference): Fix preference for objects.
* gcse.c (handle_avail_expr): Be prepared to handle single_set
parallels.
* combine.c (if_then_else_cond): Use simplify_subreg instead
of operand_subword.
* integreate.c (sub_constants): Likewise.
* emit-rtl.c (constant_subword): Deprecate; remove most of code
and use simplify_gen_subreg.

* sibcall.c (skip_copy_to_return_value): recognize the situation
when the called function's return value is copied into an
intermediate pseudo, and then into the calling functions return
value register.
