re PR rtl-optimization/15289 (reload error with non-lowpart subregs)
PR rtl-opt/15289
* emit-rtl.c (gen_complex_constant_part): Remove.
(gen_realpart, gen_imagpart): Remove.
* rtl.h (gen_realpart, gen_imagpart): Remove.
* expmed.c (extract_bit_field): Remove CONCAT hack catering to
gen_realpart/gen_imagpart.
* expr.c (write_complex_part, read_complex_part): New.
(emit_move_via_alt_mode, emit_move_via_integer, emit_move_resolve_push,
emit_move_complex_push, emit_move_complex, emit_move_ccmode,
emit_move_multi_word): Split out from ...
(emit_move_insn_1): ... here.
(expand_expr_real_1) <COMPLEX_EXPR>: Use write_complex_part.
<REALPART_EXPR, IMAGPART_EXPR>: Use read_complex_part.
* function.c (assign_parm_setup_reg): Hard-code transformations
instead of using gen_realpart/gen_imagpart.
