So far we used the minimum of the length instead of the maximum to
compute the output type of the CheckBounds, but at the same time
we never really used the output type yet.

Lexically declared "arguments" in sloppy mode will throw redeclaration error

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.
