8f54606109 ARM: Always use the overflow flag to check for NaNs participating in a floating point compare.
Looks as if we don't need to use the vcmpe instruction instead of the vcmp, as the overflow FPSCR bit suits our purpose. If we at some point need vcmpe lte's implement it as a separate instruction.

b85538bc16 Introduce two more template parameter for Lithium instructions for input and temp operands.
Each LInstruction is now a subclass of LTemplateInstruction<R, I, T>

where R is number of outputs, I number of inputs and T number of temps.

This change only actually uses the parameter I for input operands. 
Since the parameter T for temps is 0, it incurs no extra cost. 

A separate change will introduce using the temps parameter.

a7c743d3ac Reuse the gap move resolver.
Rather than allocating a fresh gap move resolver for every parallel
move, use a single one per Lithium code generator.  This avoids always
reallocating the temporary zone-allocated lists used by the gap move
resolver.

a0bc9eb040 Add more bailouts for Array.slice over arguments.
Unfortunately, arguments is pretty much the normal JS object.  For now
I am adding more sanity checks (in hope that typically arguments
list is rather short.)  However it probably requires more systematic
treatment, for example, we could optimistically copy elements until
we meet first hole and in this case resort to JS builtin.

f89ce8159a Split LInstruction into multiple variant to make our LIR more compact.
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

426f13e084 Fix GC issue in instanceof stub
The the call of the builtin in InstanceofStub was not correctly protected with an internal frame leading to the return address being handled as a pointer during GC.

Marked the Instanceof stub as allowing stub calls (the RecordWriteStub was removed some days ago).

This issue was not caught by the assertion designed for this when debug mode is run with --debug-code (which out tests always does) as generating code for Abort set the allow stub calls flag to true. This has been fixed by restoring the allow stub calls flag correctly.
