f0b8c2d97a Some cleanup of the toplevel code generator: 
* Rename the operation of filling a context with a value.  Formerly it
  was 'Move', now it's 'Apply' so as to avoid confusion with various
  other Moves (eg, in the toplevel codegen, in the macro assemblers).

* Use the abstraction Drop rather than math on the stack pointer.

* Add a predicate on AST expression nodes to abstract a repeated test
  whether we should us a regular (named) IC or a keyed IC.

3d36c712aa Use generated code to create sub strings. 
Added a stub to allocate and fill a string object with a substring from another string.

Use the rep movs instruction to copy the string data as it turned out to be the fastest way.

While preparing this I experimented with some SSE2 instructions, so the instructions movdqa and movdqu are still in the IA-32 assembler even though they are not used.

429f3cf9f2 Direct call to native RegExp code from JavaScript. 
Calls to RegExp no longer have to be via a call to the runtime system. A new stub have been added which can handle this call in generated code. The stub checks all the parameters and creates RegExp entry frame in the same way as it is created by the runtime system. Bailout to the runtime system is done whenever an uncommon situation is encountered or when the static data used is not initialized. After running the native RegExp code the last match info is updated like in the runtime system.

Currently only ASCII strings are handled.

Added another argument to the RegExp entry frame. It indicated whether the call is direct from JavaScript code or through the runtime system. This information is used when RegExp execution is interrupted. If an interruption happens when RegExp code is called directly a retry is issued causing the interruption to be handled via the runtime system. The reason for this is that the direct call to RegExp code does not support garbage collection.

e06c581232 Use cmov instructions to avoid some conditional branches in stub code. 
This change improves the ConstructStub and the ArgumentsAccessStub slightly
by using the cmov instruction (if available) to eliminate a 
conditional branch. It only applies to the IA-32 and X64 platforms.

b74daccff0 Style cleanup of switches over Slot::Type in the nonoptimizing code 
generator.

The Slot::Type enumeration has four values.  It should never be
necessary to use a default to handle the case of a value out of range
of the enumeration.  Doing so silences a useful warning when one of
the enumeration values is actually forgotten or when a new enumeration
value is added.

f7ef880041 Use a loop in generated code to allocate stack slots for function with many local variables. 
If a function contains more than a certain number of locals (IA32: 9, X64: 6, ARM: 4) 
a loop for initializing the locals with 'undefined' is more compact. 
For less locals we unroll that loop by emitting a sequence of push instructions.

This adds a code stub which can do most of what Heap::AllocateConsString can do. It bails out if the result cannot fit in new space or if the result is a short (flat) string and one argument is an ascii string and the other a two byte string. It also bails out if adding two one character strings as Heap::AllocateConsString has special handling of this utilizing the symbol table. The stub is used both for the binary add operation and for StringAdd calls from runtime JavaScript files. Extended the string add test to cover all sizes of flat result stings.

1c90793581 Fix bug in the fast compiler's object literal code 
Fixes issue 526:

BUG=http://code.google.com/p/v8/issues/detail?id=526

The object literals code in the fast compiler returned an incorrect result 
when getter or setters are defined together with computed properties.

Added a regression test that captures the most reduced version of this
problem. 

Also added a test for object literals with getters/setters and 
prototype properties.

c135f2de07 Fixed incorrect instruction usage in KeyedLoadIC for byte and word 
external array types. Added regression test based on real-world
failing code and verified that it would have caught this error.
