0fcedde224 Fix determining of JS lower stack bottom used in profiler's JS stack tracer to work with Chromium. 
My assumption that log initialization happens somewhere near the stack's bottom is true for V8's sample shell but isn't true for Chromium, causing many otherwise valid stack addresses to be thrown out. The solution proposed is to save stack pointer value for the outermost JS function in ThreadLocalTop similar to c_entry_fp.

Implemented only for IA-32. Currently I'm not dealing with profiling on ARM and x86-64 anyway.

9c829fafe9 Change the register allocator so that it no longer tracks references 
to the platform-specific reserved registers.  They are always in use
for their intended purpose, cannot appear in the virtual frame, and
can be freely used without allocation in the code generator.

01f7c87f22 This patch much improves our tracking of whether function is 
called from within a loop or not.  In the past we lost the
information if a call site went megamorphic before a lazily
compiled callee was called for the first time.  Now we track
that correctly (this is an issue that affects richards).
We still don't manage to track the in-loop state through a
constructor call, since constructor calls use LoadICs instead
of CallICs.  This issue affects delta-blue.  So in this patch
we assume that lazy compilations that don't happen through a
CallIC happen from inside a loop.  I have an idea to fix this
but this patch is big enough already.
With our improved tracking of in-loop state I have switched
off the inlining of in-object loads for code that is not in
a loop.  This benefits compile speed.  One issue is that
eagerly compiled code now doesn't get the in-object loads
inlined.  We need to eagerly compile less code to fix this.

30a0a7de43 Split nested namespaces declaration in two lines in accordance with C++ Style Guide. 
This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.
