        WebAssembly: Update spec tests
        https://bugs.webkit.org/show_bug.cgi?id=170361

        Rubber-stamped by Saam Barati.

        Update the spec tests to run tests generated by the newer spec
        test builder wasm-spec/test/builder.py. This patch also adds the
        necessary harness code in spec-harness.js so we can run the tests.

        Move slow-running microbenchmarks out of JSTests/microbenchmarks

        Reviewed by Saam Barati.
        
        The microbenchmarks directory is profitable when it's cheap to run. This change moves very slow
        tests (>=200ms running time on my machine) and puts them in JSTests/slowMicrobenchmarks instead.
        That directory is run only through `slow!; defaultQuickRun` and is not run by run-jsc-benchmarks.
        This is a big progression in test running time. But because it frontloads more slow tests, the
        tests will seem to run more slowly when you first start the test runner.

        * wasm/Builder.js: Add a Proxy to Builder.js, which intercepts
        unknown property lookups. This creates way better error messages
        on typos than 'undefined is not a function', which happens
        semi-frequently as I typo opcode names (and which one is a typo is
        hard to find because we chain builders).

        WebAssembly: Rebase spec-tests now that wabt has been updated to produce certain kinds of invalid modules
        https://bugs.webkit.org/show_bug.cgi?id=166491
        <rdar://problem/29814999>

        Reviewed by Yusuke Suzuki.

        Based off these revisions:
        - spec: b055d01ea1dfdd7a5231ae779095435f836de97f
        - wabt: d0d44702c753f851b094615298a2f4d4e3c21035

        The reason for the rebase is that wabt was updated to stop
        silently rejecting invalid modules. This was needed because
        some of the spec tests check to make sure that the module
        is invalid, but wabt was silently ignoring the errors and
        generating valid modules:
