LIQUIFY OPTIMIZATIONS V1

* This is an introduction of a BoardConfig.mk flag that will allow for us to Optimize builds like crazy.

This includes:

* Clang Optimized with -O3 Optimization
* Linker Optimizations
* Makes use of Google 4.8 Host since we track it anyways
* Graphite Flags (With call options I brought along from watching SaberMod development)
* Many other gcc flags to optimize the build also tucked away in cc-call options to keep clang from touching them and erroring out.

Note: Strict Aliasing is not included but I'll look into adding it in the future.

To use Place flag VALIDUS4LIFE=true in BoardConfig.mk of your device tree.
