Optimize the equality check case of ICCompare stubs.
...
This includes specialcasing the generation when we know that the maps
of the two objects are the same. In addition, a new specialized
compare ic known objects cache is created.
The reason for the cache is that we need to have access to the stub
code from the roots; if we do not, the GC will collect the stub. In
this specialized case we use the map pointer as key in the cache, and
we always do a lookup before generating code. Actually hitting
something in the cache will happen very rarely, but we could
potentially overwrite an existing stub, which again will lead to the
GC collecting this old stub (even if it is referenced from other code
objects)

Ensure that non-optimized code objects are not flushed for inlined functions.
...
Collector was flushing them if optimized code was reachable only through the stack (not through the JSFunction object) which happens when you have a pending lazy deoptimization.
Also prevent v8::Script::New from leaking internal objects allocated by the compiler into outer HandleScope.

Sync parser and preparser on do-while and return statements.
...
This CL fixes the preparser to have the same liberal automatic semicolon
insertion behaviour as the parser. In the case of a return statement in
global code we throw a syntax error at runtime rather than an early error
due to compatibility with KJS. However that hack allowed the following
syntactically incorrect program in global code in the parser but not in
the preparser:
if (false) return else {}
while the slightly saner version with the obligatory semicolon
if (false) return; else {}
was disallowed in the parser, but the preparser allowed it. This CL also
fixes that issue.
