Adjust fall through comments in aarch64-simd.md

[Marek Polacek]

It's unclear whether we'll handle /* Else, fall through.  */ in the nearest
future, so I'll just change it to a recognizable format instead.

When this is in, I can remove the recently added -Wno-error lines in Makefile.in.

Bootstrapped on aarch64-linux.  I'm checking this in.
