This allows us to optimized the EnsureInitialized() function
so it doesn't require a function call when we're running

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.

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.

This is intended to be used with Chromium. When in resource-saving mode, profiler doesn't consume any resources (sampler and logging is off) until resumed. Then again, when profiler is paused, sampling and logging are turned off.

When message handler is set to NULL and there is no debugger listener the debugger is unloaded immediately unless it's entered, in which case it will be unloaded when last instance of EnterDebugger is destroyed.

Without the change the debugger may crash as Debugger::EventActive(v8::Break) called from OnDebugBreak may clear current debugger context. 

Also when compilation cache was enabled debugger could fail on second attach for the same reason(see AfterCompileMessageWhenMessageHandlerIsReset).

If was failing because with snapshot the range between minimum and maximum addresses of heap objects is very large (close to 0xf0000000). To fix this I rewrote handling of address maps in the test.

Submitting with TBR because of late time. I think, we'll need to revisit this change tomorrow.

The goal is to make possible having --prof flag always enabled in Chromium.  Currently we can't do this because --prof causes compiler and gc to log code creations / moves / deletes which aren't needed until we start profiling.  With LogCompiledFunctions it will be possible not to log anything until we start profiling.  When started, the current map of compiled functions will be logged and compiler / gc logging will be enabled to update current state.  When profling is stopped, logging will be turned off again.

Funny that testing code is actually much longer and complex than function code.
