Refactor the code cache to handle large number of properties on the global object.
...
A separate object type for the code cache have been added. This object has two different code caches. The first one (default_cache) is a fixed array organized in the same way as the as the code cache was before. The second cache (global_access_cache) is for code stubs to access the global object. This cache is organized as a hash table taking the property name and code flags as the key.
The reason for separating the global access stubs into a hash table representation is that the number of these is not bounded in the same was as the other types.

Add the ability to compile with profiler guided optimizations on Windows
...
It is now possible to experiment with profiler guided optimizations when building V8. First build an instrumented sample shell:
> scons pgo=instrument sample=shell
Then run the JavaScript code to optimize for using that sample shell. Finally build an optimized sample shell.
> scons pgo=optimize sample=shell
Currently this does not work when building V8 as a DLL due to scons deleting v8.exp prior to the pgo=optimize step.
Due to a bug in Visual Studio (seen in version 2008) the function MessageDispatchHelperThread::Run() in debug.cc needs to be empty for this to work.

Make class BitField able to use 32 bits of a uint32.
...
Although algorithmically correct, the compiler would not allow to instantiate
a BitField that uses all 32 bits without warnings about a too large shift
count. As a consequence we were limited to 31 bit values when using BitField.
This happened when instantiating a bitfield BitField<T, shift, size> with
[shift=0, size=32] or [shift=31, size=1] or more general any
[shift=X, size=32-X]
As side-effect of the new implementation the compiler now warns if we ever
try instantiating a bitfield with size 0.

Introduce 'trivial' expressions, use them for this property assignments.
...
Add a (currently) syntactic predicate to AST expression nodes telling
whether they are 'trivial'. Trivial expressions have no side effects,
do not require storage to be allocated for them, and can be evaluated
out of order (because their value does not change between when they
are visited by the code generator as expressions in the AST and when
it is consumed).
Mark 'this' and literals as trivial. Allow them to be pushed on the
virtual frame. Make use of them to push 'this' more lazily in this
property assignments.
