aarch64: Reimplement URSHR,SRSHR patterns with standard RTL codes
Having converted the patterns for the URSRA,SRSRA instructions to standard RTL codes we can also
easily convert the non-accumulating forms URSHR,SRSHR.
This patch does that, reusing the various helpers and predicates from that patch in a straightforward way.
This allows GCC to perform the optimisations in the testcase, matching what Clang does.
Bootstrapped and tested on aarch64-none-linux-gnu and aarch64_be-none-elf.
gcc/ChangeLog:
* config/aarch64/aarch64-simd.md (aarch64_<sur>shr_n<mode>): Delete.
(aarch64_<sra_op>rshr_n<mode><vczle><vczbe>_insn): New define_insn.
(aarch64_<sra_op>rshr_n<mode>): New define_expand.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/simd/vrshr_1.c: New test.
