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 R=mstarzinger@chromium.org BUG=v8:7881 Cq-Include-Trybots: luci.chromium.try:linux_chromium_rel_ng Change-Id: I78a49069cfa89757cc93f0a30b1c1a99c4b2edba Reviewed-on: https://chromium-review.googlesource.com/1112003 Commit-Queue: Ben Titzer <titzer@chromium.org> Reviewed-by: Michael Starzinger <mstarzinger@chromium.org> Reviewed-by: Toon Verwaest <verwaest@chromium.org> Reviewed-by: Ulan Degenbaev <ulan@chromium.org> Cr-Commit-Position: refs/heads/master@{#54646}
