re PR target/15286 (ICE cause by reload)
PR target/15286
* final.c (alter_subreg): Compute correct offset to use with
paradoxical SUBREGs of memory operands.
* recog.c (general_operand): Allow paradoxical SUBREGs of
memory operands after reload.
* simplify-rtx.c (simplify_gen_subreg): Fail if simplify_subreg
has failed when passed a hard register.
