bbudge a933b7044a [Turbofan] Add the concept of aliasing to RegisterConfiguration. 
- Adds the concept of FP register aliasing to RegisterConfiguration.
- Changes RegisterAllocator to distinguish between FP representations
when allocating.
- Changes LinearScanAllocator to detect interference when FP register
aliasing is combining, as on ARM.
- Changes ARM code generation to allow all registers s0 - s31 to be
accessed.
- Adds unit tests for RegisterConfiguration, mostly to test aliasing
calculations.

    git pull origin
    gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
