ReportUnexpectedToken already calls Traits::ReportMessageAt. If we're in Parser,
that already suppresses the syntax error. If we're in PreParser, we don't need
to suppress the syntax error (preparser errors don't go through Isolate, and
having both stack overflow and a syntax error present is handled correctly by
PreParserApi::PreParse).

We should really split up the Lithium instruction, but this will be
done in some future cleanup CL.

Removed some "const"s for local variables on the way, they don't really
help us much and just clutter up the code.

It's possible to get a transitioned map with no links to the origin
map if it's a shared map. Code in KeyedStoreIC::StoreElementStub
assumes it can check if two maps are in the same family by
traversing the transition array. Long term, the "family" relationship
should be recognized with the Normalized Map Cache. For now, allow
the IC to remain monomorphic in this case if the receiver map and
the previous receiver map are the same.

Filed V8 issue 3210 (https://code.google.com/p/v8/issues/detail?id=3210)
to track the issue with the Normalized Map Cache.

(For more details, see bug.)

The problem occurs when a parsing function hits a stack overflow, but still
manages to return something meaningful. This happens because the call to
ParserBase::Next() which hits the stack overflow will still return a valid token
(the last token which we had already read), and only the next call after the
stack overflow will return INVALID. So for example ParseIdentifier will still
return a valid identifier even if we've hit a stack overflow.

In this case, some upper recursion level might detect and report a valid syntax
error, and then we bail out of the recursive descent because of the syntax
error. So we end up having both stack overflow and a syntax error present. When
we try to report the stack overflow after parsing (e.g., end of ParseLazy), the
isolate already has the syntax error as a pending exception, and a CHECK fails.

This fix suppresses the syntax errors in when a stack overflow has been
detected.
