Enable the use of cache. With this check-in, end-to-end LLVM milestone achieved.

For NDK samples, Plasma,
 running on Nexus-S, 800x480 screen:
  LLVM Time Run: 12.60ms per frame, Avg: 12.57
  GCC Time Run: 50.89ms per frame, Avg: 52.34

LLVM can achieve 80 fps, while GCC yields 19 fps.
GCC is visibly much slower on my Nexus-S.

Nexst step: Refactor the code and clean up.
