    [wasm] Support reftypes tables in WasmModuleBuilder · 797e4afe
    Manos Koukoutos authored
    WasmModuleBuilder is a class that is used to build Wasm modules in the
    asm.js parser, in the fuzzer, as well as some tests. When it comes to
    Wasm tables, WasmModuleBuilder currently supports only basic tables
    (before the reftypes proposal) using an ad-hoc indirect-function index
    vector.
    This CL adds proper support for element sections and tables that use
    them in the full potential of the reftypes extension. The new
    functionality will only be used in the fuzzer and potentially some tests
    in the future. Along this, we drop some functionality from
    WasmModuleBuilder that was only used in tests and is redundant with the
    new architecture.
    Additionally, we remove tables other than externref and funcref from the
    fuzzer (which were not supported properly or used anyway). We will
    reintroduce them at a later time.
