    [wasm][liftoff] Fix stack check safepoints for arm, arm64, and ia32 · 8656a594
    Andreas Haas authored
    Registers are spilled differently on arm and intel platforms.
    Additionally, on arm64 registers are spilled with padding. Therefore
    the code for safepoint information for spilled registers is platform-
    dependent now.
    
    Additionally the alignment of the frame size is done before the
    out-of-line code now, so that the safepoint indices can be calculated
    correctly for spilled registers in out-of-line code.
    
    Finally, some code was unimplemented on ia32 and arm, which I added
    now.
