Remove unused LOperands from keyed-loads. We do not have multiple representations
for load instructions anymore.
Correct number of output operands as for a couple of instructions form 1 to 0
because they do not produce a result (e.g. PushArgument)

This change introduces LTemplateInstruction which is a specialized version
of LInstruction and takes one template parameter to indicate whether the
instruction produces a result operand.
All instruction that do not have a result inherit from LTemplateInstruction<0>.
Instructions that have a result operand from LTemplateInstruction<1>
All the Define* function only operate on instructions with a result.
For this to work I also refactored the places where we do
LInstruction* result = new Lxyy
into
Lxyz* result = new Lxyz

If the instance of is performed against what is beliwed to be a constant global function inline the instance of check and have the call to the instanceof stub in deferred code. The inlined check will be patched by the instanceof stub when called from deferred code. This is indicated by the lithium instruction LInstanceOfKnownGlobal.
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.

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.
