aarch64: Handle ASHIFTRT in patterns for shrn2
Similar to the low-half patterns, we want to match both ashiftrt and
lshiftrt with the truncate for SHRN2. We reuse the SHIFTRT iterator
and the AARCH64_VALID_SHRN_OP check to help, but because we expand the
high-half patterns by their gen_* names we need to disambiguate all the
different trunc+shift combinations in the pattern name, which leads to a
slight renaming of the builtins. The AARCH64_VALID_SHRN_OP check on the
expander and the define_insns ensures that no invalid combination ends
up getting matched.
Bootstrapped and tested on aarch64-none-linux-gnu and
aarch64_be-none-elf.
