With the Indexed/GenericNamedPropertyDefinerCallback it is possible to intercept Object.defineProperty() calls.

Requests that call JSReceiver::OrdinaryDefineOwnProperty() internally, also trigger the interceptor. This includes Object.freeze(), Object.preventExtensions(), and Object.seal().

As without this patch, the query interceptor triggers on
defineProperty, unless the definer callback
intercepts the request.

The ParserTypes class has typedefs provided by the preparser or the
parser (e.g. PreParserExpression vs Expression*). Some of those typedefs
had gotten stale and were getting in the way, especially on gcc. We
also were making inconsistent use of aliases in parser-base.h; now their
use is much more consistent.

This unblocks avoiding the separate code template.
In the upcoming CL doing away with code templates, We need to track instances
through the module object, which needs to be separate from the compiled module
data, which is then shared with the first instance.

This CL ensures we have the object available in the asm.js scenario, too.

Note that this CL also unifies the error messaging when module
decoding fails.
