92bb897081 Tweaks to global object inline cache code.
Remove the check for deleted properties in the global load inline cache if the property is known to be read only.

Propegate the in loop flag for the global call inline cache.

Changed the propagation of the code flags in the call stub compiler to compute these the same way for all types of call stubs and assert that the flags for the generated code is the same as those used for the cache lookup.

Addressed a few comments from previous review in test-api.cc.

a54a4ada5c Changed the global object representation.The global object is now always in dictionary (slow) mode with each of its properties stored in a cell object. A cell object has one field containing the actual value for the property. Inline caches for access to global properties which uses direct to the cell are now created for load, store and call to properties of the global object. When properties of the global object are deleted the cell for that property is kept with an indcation of that the property is deleted.Added counters to track the use of the global property inline caches.Added additional information on IC's in the disassembler.

dfbc850ebc Revert revision 2108. This brings back the changes
submitted in revisions 2093, 2094, 2099, and 2106.
There's no evidence that supports that these changes
should be the cause of the unexplained performance
regressions on the intl2 and DHTML page cyclers.

84c09c6de4 Experimental revert of revisions 2093, 2094, 2099, and
2106 to try to isolate a performance regression on the
page cyclers.

I'll roll the changes back in if this doesn't fix the
regression.

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.

ea48d53bad Add ENABLE_DEBUGGER_SUPPORT macro.
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.

c093e94546 - Pass the knowledge whether the old GC is compacting to the GC prologue and epilogue. This allows us to skip frame cooking and uncooking when doing a mark-sweep GC.
- Add the ability for the code to refer to its code object by adding a handle to the code object in the MacroAssembler.

0fc72f2b4e Serendipitously arrange the tags so that String.length() becomes a branch-free
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.

70dcba4024 Exclude the bit-field bits from string hash codes. String hash codes
are always odd if the bit-field bits are included.

Modified a couple of debugger tests that relied on the ordering of
elements in descriptor arrays.  Descriptor arrays are sorted by
hash-code values, so the order changes if we change the hash code.
