re PR middle-end/54315 (unnecessary copy of return value for union)
PR rtl-optimization/54315
* calls.c (expand_call): Don't deal specifically with BLKmode values
returned in naked registers.
* expr.h (copy_blkmode_from_reg): Adjust prototype.
* expr.c (copy_blkmode_from_reg): Rename first parameter into TARGET and
make it required. Assert that SRCREG hasn't BLKmode. Add a couple of
short-circuits for common cases and be prepared for sub-word registers.
(expand_assignment): Call copy_blkmode_from_reg for BLKmode values
returned in naked registers.
(store_expr): Likewise.
(store_field): Likewise.
