aarch64: PR target/99195 Annotate saturating mult patterns for
vec-concat-zero
This patch goes through the various alphabet soup saturating multiplication
patterns, including those in TARGET_RDMA
and annotates them with <vczle><vczbe>. Many other patterns are widening
and always write the full 128-bit vectors
so this annotation doesn't apply to them. Nothing out of the ordinary in
this patch.
Bootstrapped and tested on aarch64-none-linux and aarch64_be-none-elf.
