Also check more than one character at a time.
16-bit immediates requires a prefix that changes the length of the instruction.
This causes predecoder mispredictions and subsequent pipeline stalls.
Also removed redundant "atStart" local variable which is equivalent to startIndex == 0.

of having a list of virtual frame pointers in the jump
target we have one virtual frame, which is the frame that
all have to merge to to branch to that frame.  The virtual
frame in the JumpTarget is inside the JumpTarget, rather than
being an allocated object that is pointed to.  Unfortunately
this means that the JumpTarget class has to be able to see
the size of a VirtualFrame object to compile, which in turn
lead to a major reorganization of related .h files.  The
actual change of functionality in this change is intended
to be minimal (we now assert that the virtual frames match
when using JumpTarget instead of just assuming that they do).

The change r4608 accidently disabled the inlined keyed load as the key/receiver registers was mixed up. Also make sure that the registers for the keyed load IC is not clobbered before bailout to deferred code. This adds one instriction to the inlined code path.

This change allows Object.create to take a function as input in the
proto argument. The spec says that Type(O) for the proto argument
should be true but our IS_OBJECT does not check for this. I will make a
IS_SPEC_OBJECT in macros.py and refactor v8natives in another CL.
