    [wasm] [asm.js] Track direct function indices and fixup. · cfed56c2
    bradnelson authored
    Recent changes to the wasm format prevent you from knowing
    the function index of a direct call until you know how many
    imports you have (the index spaces have been merged).
    
    Asm.js validation can't know this until all callsites have been
    visited if you want to avoid materializing the entire AST / parsing twice.
    Instead, keep a list of fixups to perform for all direct callsites,
    then update these with the imports count added when emitting the module.
