Optimizations, Toolchain separations, and cleanup.

Gonna keep it short and simple. The commits here:
- Add a bunch of optimizations (if ELECTRIFY=true is either exported or added to ~/.bashrc)
- Add Graphite loop optimizations (if SaberMod toolchain is detected)
- Separate deffinitions for arm-eabi and androideabi toolchains
- Cleanup armv7-a-neon.mk
- Cleanup dumpvar.mk
- Cleanup emulator.mk
