a77d81c59b Fix a failure to correctly set the static type on a frame element at a 
backward jump.  The frame entering the backward block is not used, so
the this is mostly just a bookkeeping change.

ef85ba46b0 First round of size reduction for JumpTargets. Reduce their size by 
two words: there is no reason to keep a pointer to the current code
generator and macro assembler in the JumpTarget.

f4778b007f Reduce the memory used by frame elements from two words to one by 
encoding the values in one word and by using an indirection table for
handles.

This reduces compilation time by roughly 10% and we should be able to make the slow case equality checking of frame elements faster as well.

5fab2d08f2 A register allocation bugfix. 
The function that prepares a virtual frame slot for writing (in order
to preserve the copy-on-write semantics of aliased frame elements) can
allocate registers, which may spill one from the frame.  If we're
unlucky, the spilled register can be the source register for the frame
element write.  In that case, ensure we do the write from memory.

ecd705813f A simple fix of issue http://code.google.com/p/chromium/issues/detail?id=3285 
NPN_Construct allows a NPObject to be called as a construct. For example, the
test case

var s = new app.Packages.java.lang.Integer(5);

app.Packages.java.lang.Integer is a NPObject, and it implements NPN_Construct.

This fix allows a JSObject created by an API function be called as a construct
if it can be called
as a function. This is done by generating the same code for
var s = new app.Packages.java.lang.Integer(5); as
var s = app.Packages.java.lang.Integer(5);

and the caller handles both case correctly. A more sophiscated fix is to one
extra JSConstructCall
frame and allow CallAsConstructor in Builtin::HandleApiCallAsFunction.

This change itself shouldn't affect the semantic of normal case such as:

var a = {};
var s = new a();

A TypeError exception will be thrown in CALL_NON_FUNCTION (runtime.js).

Another part of fix is in the binding code, V8NPObject, which makes
NPN_InvokeDefault or NPN_Construct
call depending on which function is available.

Flat strings can be sliced or cons strings that have a flat

it is ASCII or not we should ask the underlying string about
its representation.  This should fix

cc0c8d178f Materializing a frame element on the stack by pushing it can cause the 
stack pointer to change by more than one in a corner case.  If we push
a constant smi larger than 16 bits, we push it via a temporary
register.  Allocating the temporary can cause a register to be spilled
from the frame somewhere above the stack pointer.

As a fix, do not use pushes to materialize ranges of elements of size
larger than one.
