(emit_move_insn_1): Move MODE_DECIMAL_FLOAT modes by invoking
emit_move_via_integer.

* expr.c (emit_move_resolve_push): Handle PRE_MODIFY
and POST_MODIFY with CONST_INT adjustment equal to PUSH_ROUNDING.
Fix POST_INC/POST_DEC handling if PUSH_ROUNDING is not identity.
* config/i386/i386.md (pushhi2, pushqi2): Use pushl instead of pushw.
Set mode to SI, adjust constraints.
(pushhi2_rex64, pushqi2_rex64): Set mode to DI.
* config/i386/i386.h (PUSH_ROUNDING): Round up to 4 instead of 2 for
32-bit code.

* expr.c (emit_move_via_integer): Add force argument, pass it on
to emit_move_change_mode. Update callers.
(emit_move_complex): Pass true to new force argument.
* function.c (expand_function_end): Move expand_eh_return call
earlier. Merge sub-word complex values into a pseudo before
copying to the return hard register.

* expr.c (expand_expr_real) <normal_inner_ref>: Force op0 to mem
when we would be extracting outside its bit span (bitpos+bitsize
larger than its mode), possible with some VIEW_CONVERT_EXPRs from
Ada unchecked conversions.
