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.

For keyed IC loads setting a break point now ensures that the inlined code is not used. When the break point is set the inlined map check is changed to fail causing the inlined code not to be used but the IC to be called. As long at the break point is set the map check will stay invalid.

ENABLE_DEBUGGER_SUPPORT is enabled by default unless it is on Android platform.
On Android platform, it can also enabled by passing -DENABLE_DEBUGGER_SUPPORT flag to the compiler.
This should not affect any existing build (I hope, cross my fingers) except the build in real Android environment (in other word, it only affects me now).
There are lot of room for code refactoring in stead of using #ifdef all over the place. I will leave this to v8 folks.

calling a stub. The map to check against is unknown when generating
the code, so we patch the map check in the IC initialization code.
Loop nesting is currently not tracked on ARM. I'll file feature
request bug reports for implementing this on ARM and add the number to
the TODOs before I commit.

operation. I have another version of this change that does not remove the
special inline caches for difference sized strings. The other version is ever
so slightly faster, but the nice thing about this version is that it removes
253 lines of code.

ExtendStorage did not work with keyed store IC.
- Reduced instructions generated when performing a tail call to
kSharedStoreIC_ExtendStorage
- Moved test/mjsunit/bugs/bug-109.js

upper case. Moved it into the RelocInfo class together with the associated
is_xxx functions. Renamed is_xxx to IsXxx in the process.
Removed the exit_js_frame mode as it was no longer used.
Patch Set 2 renames RELOC_MODE_COUNT to NUMBER_OF_MODES and fixes a couple of lint errors.

occured. After a monomorphic prototype failure has been detected,
other monomorphic inline caches for the same type will have a code
object in the map's code cache which is not the current target. We
recognize this case and use the code object that is in the cache
instead of going megamorphic.

Cleaned up ARM version by removing top of stack caching and by introducing push/pop elimination.
Cleaned up the way runtime functions are called to allow runtime calls with no arguments.
Changed Windows build options to make sure that exceptions are disabled and that optimization flags are enabled.
Added first version of Visual Studio project files.
