This patch adds support for `-m[no]fpf16`, ` `-m[no]fpf16fml` and
`-m[no]dotprod` feature flags for ARM.

The flags behave similar to specifying an -march flag with
+/-{fp16,fp16fml,dotprod}, but is more convenient for users that do not
want to provide a specific architecture version. There are similar flags
alread, like `-mcrc`.
