* expr.h (copy_blkmode_to_reg): Declare.
* expr.c (copy_blkmode_to_reg): New function.
(expand_assignment): Don't expand register RESULT_DECLs before
the lhs. Use copy_blkmode_to_reg to copy BLKmode values into a
RESULT_DECL register.
(expand_expr_real_1): Handle BLKmode decls when looking for promotion.
* stmt.c (expand_return): Move BLKmode-to-register code into
copy_blkmode_to_reg.
