aarch64: PR target/99195 annotate simple narrowing patterns for vec-concat-zero
This patch cleans up some almost-duplicate patterns for the XTN, SQXTN, UQXTN instructions.
Using the <vczle><vczbe> attributes we can remove the BYTES_BIG_ENDIAN and !BYTES_BIG_ENDIAN cases,
as well as the intrinsic expanders that select between the two.
Tests are also added. Thankfully the diffstat comes out negative \O/.
Bootstrapped and tested on aarch64-none-linux-gnu and aarch64_be-none-elf.
gcc/ChangeLog:
PR target/99195
* config/aarch64/aarch64-simd.md (aarch64_xtn<mode>_insn_le): Delete.
(aarch64_xtn<mode>_insn_be): Likewise.
(trunc<mode><Vnarrowq>2): Rename to...
(trunc<mode><Vnarrowq>2<vczle><vczbe>): ... This.
(aarch64_xtn<mode>): Move under the above. Just emit the truncate RTL.
(aarch64_<su>qmovn<mode>): Likewise.
(aarch64_<su>qmovn<mode><vczle><vczbe>): New define_insn.
(aarch64_<su>qmovn<mode>_insn_le): Delete.
(aarch64_<su>qmovn<mode>_insn_be): Likewise.
gcc/testsuite/ChangeLog:

* gcc.target/aarch64/simd/pr99195_4.c: Add tests for vmovn, vqmovn.
