When reparsing the class scope to collect initializers in sloppy mode,
the class scope may still have a scope info without any allocated
variables. If its outer scope doesn't have an outer scope (which means
the outer scope in the optimized scope chain becomes the script scope),
we should also set the scope info in the script scope as is done
in Scope::DeserializeScopeChain() for the scope resolution.

This patch takes advantage of memory information from the module
to avoid unnecessary reloads of the SSA environment after a Wasm call.

As far as I can sse, the SSA envinronment consists of the mem_start
and mem_size values. Both these values cannot ever change if:

	initial_mem_size == max_mem_size.

Although this should be obviously true for memories defined in the
module itself, some explanation may be necessary for imported memories.

During module instantiation, the imported memory is checked as part of
InstanceBuilder::ProcessImportedMemory. The following properties are verified:

1) The current size of the imported memory is >= the initial declared size
2) The maximal size of the imported memory is <= the maximal declared size

The effective maximal limit will be min(imported_max, declared_max),
hence the optimization will only trigger if the imported memory is
already as large as it can be.

Since memory growth is impossible, there is no point in reloading the
environment anyway.

1) when generating short builtin calls/jumps assemblers should use the
   offset from the CodeRange base rather than the start of the code

   range base in the following cases:
     * when the "base bias size" is non-zero (on Windows 64),
     * when we ended up over-reserving the address space for the code
       range, which happens as a last resort to fulfil the CodeRange
       alignment requirements.
   See the VirtualMemoryCage description for details.

Drive-by fixes:
2) in case of over-reserving address space for external code range,
   the pre-calculated hint for where the remapped embedded builtins
   should be copied to was outside of the allocatable CodeRange region
   and thus useless. The fix is to use the allocatable region instead
   of the reservation region when calculating the hint.
3) when allocating CodeRange with zero base bias size we can create
   the VirtualMemory reservation from the first attempt simply by
   passing the required base alignment to the VirtualMemory
   constructor.

Use DescriptorArray::Set instead of Append to avoid resorting the
descriptors for every newly added property

Map::Hash relies on the fact that the map space is never compacted.
However this might change in the future, so instead of using the
address of the prototype's map, we use the prototype's identity hash
instead.

Exports are properties in the global object. Pre-reserve the space,
since we know the count upfront.
