    [wasm] Remove trap handler fallback · c2835df6
    Clemens Hammacher authored
    The trap handler fallback is flaky, and was never enabled since it
    never worked reliably. This CL removes
    a) the --wasm-trap-handler-fallback flag,
    b) the distinction between soft and hard address space limit,
    c) methods to check whether memory has guard regions (it will always
      have them on 64 bit architectures),
    d) associated runtime functions,
    e) the trap handler fallback tests,
    f) recompilation logic for the fallback.
