Log:
    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.
