This patch fixes a failure in gcc.target/aarch64/reload-valid-spoff.c 
triggered by https://gcc.gnu.org/ml/gcc-patches/2017-06/msg01367.html.

In ILP32 all memory accesses must have Pmode as the base address, but
aarch64_expand_mov_immediate wasn't emitting a conversion in one case.
Besides fixing this add an assert that flags any MEM operands that are
not Pmode.

    gcc/
	* config/aarch64/aarch64 (aarch64_expand_mov_immediate):
	Convert memory address to Pmode.
	(aarch64_print_operand): Assert MEM operands are always Pmode.
