0f66199b5e Heap profiler: remove context checks for objects. 
It seems that there will be no access to heap snapshots from
web pages' code, only from Developer Tools, thus it makes no
sense doing filtering of object by their security contexts.

f386f97476 Move part of scanner.* into scanner-base.* for reuse in preparser scanner. 
Make checks.h not depend on flags.h or global.h (or anything else except
include/v8stdint.h). Only checks.cc has the dependencies (so another
implementation of checks.cc can be provided by the preparser).
Now files depending on checks.h (using ASSERT macros) can include it
directly without depending on all of v8.

20938fc53c Attempt to collect more garbage before panicking with out of memory. 
Currently weak handles retain an object for another GC round (oftem times,
major GC round.)  Instrumenting Chromium shows that navigation leaves
many global objects which are only collected in next go.  Let's
attempt to collect more garbage when approacing OOM condition.

This is a better version of rolled out r5455: now it's correctly
rebuilds object groups between additional GCs.

46951e659c Landing for Justin Schuh. 
This switches out the existing constant splitting with masking that works like this:

1. Generate a random 32-bit value at compilation time.
2. XOR the 32-bit constant with the random value.
3. Emit the resulting immediate value along with the XOR operation to generate the original value.
