Disables NEON optimized instructions.

These are causing issues in games. In particular you get pink on the screen in Animal Crossing.
Disable until fully investigated.

This also disables fastmem on floating point loadstore instructions which are horribly broken and won't actually backpatch when an invalid read/write
is encountered.
