explow.c (convert_memory_address): Fix conversion of CONSTs.
* gcc/explow.c (convert_memory_address): Fix conversion of CONSTs.
Fix permutation of conversion and plus/mult.
* gcc/builtins.c (expand_builtin_memcpy) Ensure return pointer is
ptr_mode and not Pmode when POINTERS_EXTEND_UNSIGNED is defined.
(expand_builtin_strncpy) Ditto.
(expand_builtin_memset) Ditto.
