aarch64: Add missing %z prefixes to LDP/STP patterns
For LDP/STP Q, the memory operand might not be valid for "m",
so we need to use %z<N> instead of %<N> in the asm template.
This patch does that for all Ump LDP/STP patterns, regardless
of whether it's strictly needed.
This is needed to unbreak bootstrap.
