To help the patching the delta from the return address to the patch site is placed just below the return address in the edi slot of the pushad/popad ares. This is safe because the edi register (which is pushed last) is a temporary for the lithium instruction.

As the instanceof stub can call other JavaScript an additional marking for saving all double registers have been added.

Also tweaked the instanceof stub to produce true/false objects instead of 0/1 for the case with deferred code.

Optimize array-length and fast element loads.

1. Separating out the instance-type check from the array-length operation.

2. I also changed the bounds-check on keyed loads to use the length property
for JS arrays (like we do for array stores).

The new pattern should use less registers and allow more checks to be eliminated.

Fix issue 977, occasional failure of the DeltaBlue benchmark.

Before, when we deoptimized after a branch we jumped to before the branch
was taken in the unoptimized code with a token value that indicated when
edge to take.  There was a lot of machinery to track this value through the
short-circuit logical operations and logical negation, and to handle it
properly at inline function return sites.  There was also machinery to
prevent incorrectly seeing this environment with the extra value never
actually materialized in the unoptimized code.

Instead, now we deoptimize directly to one of the targets of the branch.
Much but not yet all of the extra machinery has been removed or simplified.
The cost is that branching control structures (the looping statements, if
statements, conditional expressions, and the short-circuit binary logical
operations) need extra AST IDs to identify the branch targets.
