5751d8f50c Avoid a potential null dereference wrt the CPU profiler. 
GetActiveProfilerModules()/PauseProfiler()/ResumeProfiler() can be reached
from the API when the --prof runtime flag is not set, leading to null
dereferences. Verify that Logger::profiler_ is non-NULL before using it.

8ab6832203 Add "has fast elements" bit to maps and use it in inlined keyed loads. 
A potential issue with this change is creating lots of maps when
objects flip between fast/slow elements modes.  We could add special
transitions to avoid this.  Yet testing this on our benchmarks, gmail,
and wave seems to indicate that this is not a real problem.

ae39e059c2 Take survival rates of young objects into account when choosing old generation limits. 
Stable high survival rates of young objects both during partial and
full collection indicate that mutator is either building or modifying
a structure with a long lifetime.

In this case we aggressively raise old generation memory limits to
postpone subsequent mark-sweep collection and trade memory space
for the mutation speed.

927750571c Remove redundant checks in and around GenerateDictionaryLoad. 
Similar or duplicate checks are scattered around the code before doing the dictionary load. 
Also the entire branch in GenerateCallNormal that handles global/builtin receiver is 
guaranteed to bail out from GenerateDictionaryLoad, so there is no point in generating it at all.

The purpose of the patch is:
- making C++ code more compact and transparent,
- not generating dead code. 

There is a tiny performance gain. The patch is ia32 only for now.

Please tell me if I am missing anything.
