The actual allocatable size still depends on the allocator;
in particular Blink's ArrayBufferAllocator is currently limited
to 2GB.
WebAssembly memories are not affected by this change (i.e. still
capped at 2GB as well).
For 32-bit platforms, the limit remains at 2**30-1 (=max smi) elements.

This makes sure instantiate of asm.js modules fails gracefully on heap
buffers exceeding the uint32_t range supported by WebAssembly.
