simplify-rtx.c (simplify_subreg): In the CONCAT case...
* simplify-rtx.c (simplify_subreg): In the CONCAT case, check whether
the request subreg is entirely contained in the requested component.
(simplify_gen_subreg): Return null for CONCATs that are rejected
by simplify_subreg.
* expmed.c (store_bit_field): Create a temporary when changing the
value to an integer mode.
