aarch64: Simplify QSHRN expanders and patterns
This patch deletes the explicit BYTES_BIG_ENDIAN and !BYTES_BIG_ENDIAN patterns for the QSHRN instructions in favour
of annotating a single one with <vczle><vczbe>. This allows simplification of the expander too.
Tests are added to ensure that we still optimise away the concat-with-zero use case.
Bootstrapped and tested on aarch64-none-linux-gnu and aarch64_be-none-elf.
gcc/ChangeLog:
* config/aarch64/aarch64-simd.md
(aarch64_<sur>q<r>shr<u>n_n<mode>_insn_le): Delete.
(aarch64_<sur>q<r>shr<u>n_n<mode>_insn_be): Delete.
(aarch64_<sur>q<r>shr<u>n_n<mode>_insn<vczle><vczbe>): New define_insn.
(aarch64_<sur>q<r>shr<u>n_n<mode>): Simplify expander.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/simd/pr99195_5.c: New test.
