aae7033ba1 Fix JavaScript accessors on objects with interceptors. 
This fixes how Object.defineProperty() defines JavaScript accessors on
objects with installed API interceptors. The definition itself does not
cause any interceptors to be called, whereas any subsequent accesses on
said object will still fire the interceptor. This behavior is in sync
with API accessors.

410219c8f3 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.

e2f2c77e6f Be more willing to expand old space when evacuating new space at the end of 
a mark-sweep.  We have a soft limit on old space size, which is designed to
trigger an old-space collection when we hit it.  Unfortunately although the
soft limit had already triggered an old space collection, the soft limit was
preventing objects from new space from being promoted.  For every promotion
candidate we were checking 3 different ways to allocate in old space before
giving up and putting the object in the other semispace.  This change allows
the promoted objects to go to old space and also makes us more eager to
sweep a page before trying other ways to find space for an object.
