[Compiler] use Art indentation standard

First of several CLs to bring code closer to alignment with Art and LLVM
standards.  Move to 2-space indenting.  Sticking with 80-col line
length (which LLVM apparently also wants).  LLVM also prefers camel
case names, so keeping Dalvik convention there as well (for now).
