re PR debug/70628 (ICE in get_reg_rtx, at emit-rtl.c:1025)
PR debug/70628
* rtl.h (convert_memory_address_addr_space_1): New prototype.
* explow.c (convert_memory_address_addr_space_1): No longer static,
add NO_EMIT argument and don't call convert_modes if true, pass
it down recursively, remove break after return.
(convert_memory_address_addr_space): Adjust caller.
* simplify-rtx.c (simplify_unary_operation_1): Call
convert_memory_address_addr_space_1 instead of convert_memory_address,
if it returns NULL, don't simplify.
* gcc.dg/torture/pr70628.c: New test.
