      [wasm] Prepare to support 4GiB memories · dab10765
      Ben L. Titzer authored
      This is a preparatory CL that refactors the WASM memory allocation path,
      the WasmGraphBuilder, and several points of contact for ArrayBuffers to
      allow them to eventually be up to 4GiB.
      
      1.) Refactor definition of constants to prepare for memories of size 2^32
      2.) Refactor WasmInstanceObject fields memory_size and memory_mask to
          be stored as uintptr_t
      3.) Refactor WasmGraphBuilder to use 64-bit comparisons for bounds checks
      4.) Refactor JSArrayBuffer accessor methods to use size_t properly.
      5.) Add empirical maximum memory and array buffer size tests
