    PPC: Push the full q register before lazy compile · d913f046
    Milad Fa authored
    V8 uses the same set of fp param registers as Simd param registers.
    As these registers are two different sets on ppc we must make
    sure to also save them when Simd is enabled.
    Check the comments under crrev.com/c/2645694 for more details.

    Original Commit Message:
    
        If a lazy compilation happens in between 2 Wasm calls, we need to save
        the full Q register, since we can have live v128 values.
