[PATCH v2 1/3] aarch64: Add command line support for armv9.5-a

[Andrew Carlotti]

---

I've added a test that I accidentally omitted from the v1 patch.  I've also
made the changes Richard requested for the whole patch series.  I'll push this
once my regression test finishes if there aren't any issues raised before then.


gcc/ChangeLog:

        * config/aarch64/aarch64-arches.def (V9_5A): New.
        * doc/invoke.texi: Document armv9.5-a option.

gcc/testsuite/ChangeLog:

        * gcc.target/aarch64/simd/armv9p5.c: New test.
