Port 556e4859

Original Commit Message:

    Instead of storing the values of the single precision floating point registers,
    get their values from the aliased double precision registers.

    This saves, on arm64, 184 bytes per deoptimisation kind function (552 in total)
    and 128 bytes in the RegisterValues class.
