    [wasm] Fix code specialization for empty memory buffer · 7d8a3028
    Clemens Hammacher authored
    From asm.js code we might get an empty ArrayBuffer as heap memory. In
    this case, both the old memory start and the new memory start will be
    nullptr. The size however has to be patched from default_size to 0.
    
    This CL changes code specialization to be able to either patch memory
    references, or patch memory sizes or both.
