* emit-rtl.c (validate_subreg): New.
(gen_rtx_SUBREG): Use it.
* simplify-rtx.c (simplify_subreg): Likewise.
(simplify_gen_subreg): Likewise. Remove duplicate asserts.
* expr.c (emit_move_insn_1): Tidy complex move code. Use memory
fallback whenever gen_realpart/gen_imagpart would not be able to
create SUBREGs.
