[gas][aarch64] Turn on SVE when using f32mm or f64mm extensions
There are no instructions under these matrix multiply extensions that can be used without having SVE enabled. Since these extensions require SVE, we make that explicit in the options table. Tested on aarch64-none-elf without regressions. gas/ChangeLog: 2020-01-13 Matthew Malcomson <matthew.malcomson@arm.com> * config/tc-aarch64.c (f64mm, f32mm): Add sve as a feature dependency.
