e61bd7bd26 ARM: backend opt for ToBoolean: JIT code generation for ToBool 
Upgraded the CodeGenerator::ToBoolean() function in the ARM backend to use complete JIT code generation and not make runtime calls to ToBool (when VFP is enabled). 

This change also includes the vcmp VFP instruction that supports a constant 0.0 as the second operand.

0ee0a36e72 Add last OS error into heap stats. 
That could allow us to understand why commit of from space sometimes fails.
Another option would be start a separate structure with OS-related info, but
as it's a single field, let's put it into HeapStats, at least for now.

421db370d9 Preserve constant function transition when adding the same function. 
This should help in cases like:
function Constructor() {
  this.foo = constFunction;
  this.bar = "baz";
}

for (...) {
  o = new Constructor();
  // Constant call IC will work.
  o.foo();
  // Inlined property load will see the same map.
  use(o.bar);
}

This change also fixes a latent bug in custom call IC-s for strings
exposed by string-charcodeat.js.

8e0cd6db8a Handle overwriting valueOf on String objects correctly when adding 
This adds a check to the fast case string add to ensure that the String object still have the default valueOf function. The default valueOf is sitting on a hidden prototype of String.prototype.

Before using the fast case valueOf the object is checked for a local valueOf property. For slow case objects this check always reports true (the dictionary is not probed, so valueOf might be there) and for fast case objects the descriptor array is checked for the valueOf symbol (just liniar scan). After that the prototype is checked for beeing the initial value of String.prototype. If this all pass (that is the default valueOf is still in place) this result is cached on the map making the check fast the next time.

This is only implemented in the optimizing compiler, as the two usages of %_IsStringWrapperSafeForDefaultValueOf is never hit by the full compiler.

I will port to x64 and ARM when this has been reviewed for ia32.

I will remove the performance counters prior to final commit.

36e5743674 Put direct code pointers into JSFunction objects. This is a first step 
in allowing more flexible compilation and to simplify builtins lookup. 

This changes a number of places where code objects are assigned to
SharedFunctionInfo objects to also assign this code object to the
JSFunction. In addition, the code flushing is changed slightly to
accomodate this (we need to flush the code from functions pointing to
SharedFunctionInfo objects that has already been flushed).

57769489d5 First phase of migration to new indexed property query callbacks. 
Eventually indexed property query callbacks will return attributes
(as an integer) or an empty handle if property is not intercepted.

To gradually migrate to this new API, USE_NEW_QUERY_CALLBACK
macro would control if old or new style API is used.

So the migration plan is:

1) introduce new API which should be explictily enabled;
2) switch to new API defining USE_NEW_QUERY_CALLBACK before
include of <v8.h> (that would require changes to client code as well)
3) remove old API from v8
4) remove #define USE_NEW_QUERY_CALLBACK from clients.

Changes necessary to following ES5 semantics and matching Safari - in ES3
the same RegExp object was generated by each evaluation of the RegExp literal.
Fixes bug 704.

70d3296087 Reapplying r5174 (Avoid GC when compiling CallIC stubs).

The new patch just fixes the actual problem (GC triggered while raw pointers
are held in LookupResult).
