    [Turbofan] Add the concept of aliasing to RegisterConfiguration. · a933b704
    bbudge authored
    - 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.
