The "Address" type is V8's general-purpose type for manipulating memory
addresses. Per the C++ spec, pointer arithmetic and pointer comparisons
are undefined behavior except within the same array; since we generally
don't operate within a C++ array, our general-purpose type shouldn't be
a pointer type.

Merge the outer_scope_info and feedback_metadata fields on
SharedFunctionInfo. outer_scope_info is only used during parsing,
and feedback_metadata is only available after compilation, so the
two never exist at the same time. Thus, they can share a field slot.
The exception is un-compiling and re-compiling a function, where we
need the outer_scope_info again. Fortunately, the outer_scope_info
can be re-calculated from the SFI's scope_info.

The WasmModuleObjectBuilder was the first interface for streaming
compilation of WebAssembly. Over time we realized that the interface
is insufficient, and we introduced the WasmModuleObjectBuilderStreaming
class, which is used now for streaming compilation. Since the
WasmModuleObjectBuilder was never fully functional, I think it is okay
to remove it without a deprecation period.

We don't need to pay the cost of going to JS to simply stamp out a

Most of the users of these api methods manually ensure that the returned
values are Strings. With an additional flag we can easily ensure that already
in V8 and avoid needless api roundtrips.
