(new Int8Array((new WebAssembly.Memory({initial: 0})).buffer)).buffer;
[typed arrays] GetBuffer returns old buffer for guarded buffers This also adds a DCHECK that the buffer does not have guard pages in MaterializeArrayBuffer because the code there does not know how correctly set up a buffer with guard pages.

[wasm] fix js-api Memory and Table constructor Fix and re-enable tests for WebAssembly's memory/constructor and table/constructor js-api. It introduces the '[EnforceRange] unsigned long' algorithm used to validate initial and maximum properties. The initial property is now required, by the switch to the Web IDL specification. Most of the input validations errors are now considered TypeError instead of RangeError. The WasmTableObject and WasmMemoryObject APIs use more consistently uint32_t to ensure integer range and remove the need for bounds checks.
