496868722f Added fast support for Math.pow. This simply calculates the result using the 
same method as the old powi version in runtime.cc and also checks if
the exponent is 0.5 or -0.5 in which case we calculate the square root or 
reciprocal value of the square root.

893637a057 Inlining a few virtual frame functions. 
Introducing a virtual-frame-inl.h file containing some platform-independent
virtual frame function which are small enough to be inlined.

Removed unnecessary #include of virtual-frame.h from register-allocator-inl.h
and added the necessary explicit includes in a number of files.

8398287070 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.

7f11d46363 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.

d955c20beb Fix reliability crash caused by wrong assert. 
These two asserts in ComputeEntryFrame are wrong since the
virtual frame already knows how to deal with the number type
information of copy elements: We do not store type 
information with copy elements. Instead the backing element
contains the type information.

Original review: http://codereview.chromium.org/646010/show

Change the implementation of lastIndexOf method of String. Convert the
strings in question to Vector<char> or Vector<uc16> and execute simple
search algorithm on them.

The difference in speed on 500k character string is about 10x.

a9202fc45d Begin using a list of bailouts instead of a singleton in the fast code generator. 
A list of bailout descriptions is kept in the CompilationInfo
structure that is shared between the primary and secondary code
generators.  The primary adds a description to the list for each
bailout position.

Responsibility for binding labels is moved from the primary to the
secondary code generator. All the labels still target the start of the
secondary code and the compilation state of the primary is still
ignored.

Move the compilation mode flag to the CompilationInfo.

ec86513519 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.

226769d8bf Temporarily move the ia32 fast code generator into the platform-specific directory. 
This allows us to make changes to one platform without affecting the others.

e1041c9f9c 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.
