gas, aarch64: Fixes in texi and tests following faminmax and lut changes

Making two cleanups that came out of the comments from my previous
patches:
1. Fixing `c-aarch64.texi` file so that the AArch64 architecture
   extensions are ordered alphabetically.
2. Fixing faminmax test cases so that they follow the existing test
   conventions.
