We currently only expose this to desugarings and not in the grammar

A side-effect of this change is that it is now possible to use a

Add codegen support for up to 4GiB memories in Liftoff code.

This CL also adds three new mjsunit tests that stress large WASM
memories (1, 2, and 4 GiB) and checks that accesses near these
boundaries properly generate traps.

Note there is still some trickiness around the setting of:
  1.) the flag --wasm-max-mem-pages
  2.) wasm-limits.h kSpecMaxWasmMemoryPages = 65536
  3.) wasm-limits.h kV8MaxWasmMemoryPages = 32767

In particular, the allocation of memories is still limited to
3.) and the runtime flag can only lower this limit.

The above means that the tests for 2GiB and 4GiB memories will silently
OOM by design until 3.) is changed (though they currently pass with
manual testing). I argue it is better to include these tests up front,
since they will immediately trigger if their memory allocation succeeds.

Therefore the plan is to lift the restriction on 3.) after removing
all other other internal V8 limitations including array buffers and views.

Previously we used the start address of the AbstractCode object. This
doesn't make sense for off-heap builtins, where the code isn't contained
in the object itself. It also hides other potential problems - sometimes
the sample.pc is inside the AbstractCode object header - this is
never valid.

There were a few changes necessary to make this happen:
  - Change the interface of CodeMoveEvent. Now 'to' and 'from' are both
    AbstractCode objects, which is nice because many users were taking
    'to' and adding the header offset to it to try and find the
    instruction start address. This isn't valid for off-heap builtins.
  - Fix a bug in CodeMap::MoveCode where we didn't update the CodeEntry
    object to reflect the new instruction_start.
  - Rename the 'start' field in all of the CodeEventRecord sub-classes
    to make it clear that this is the address of the first instruction.
  - Fix the confusion in RecordTickSample between 'tos' and 'pc' which
    caused pc_offset to be calculated incorrectly.

The bots currently have another problem with webkit_unit_tests and
don't run the layout tests on every revision. Hence the speculative
revert.
