3af35dc96f Optimize functions needing a local context. 
Allocate the context in the prologue. Two issues had to be solved:
(1) deoptimization needs to handle functions with a local context,
(2) we need a safepoint in the prologue.
(Thanks to Kevin.)

0a15b9116a X64: Refactor the string add in the type recording binary operation stub 
This makes the code have the same structore as on IA32 and ARM, and will also support possible fast adding a smi and string where the string is to the right and fast adding of String objects.

2ab5691ac1 ARM: Add support for just one string argument in the string add stub 
Having a string add stub which can handle a string in just one of the arguments is essencial for the type recording binary operation stub when expecting strings. Otherwise string added with e.g. smi will always call the runtime for a type transition which will be back to the same types as the transition code keeps it in string arguments when one argument is a string.

This fixes the regression (especially Delta Blue) caused by replacing the generic binary operation stub with the type recording binary operation stub in the ARM lithium code generator.

2e08148b06 Fix the semantics of delete on parameters. 
Before, an attempt to delete a parameter in a function that used the
arguments object in any way would succeed with true and delete both
the parameter and the corresponding arguments object property.

Now, an attempt to delete such a parameter does not delete and
evaluates to false.

Parameters can be deleted, as before, from functions that use the
arguments object, by deleting the corresponding arguments object
property (this is a spec violation).

dabc590527 ARM: Add type-feedback recording for compare 
Change the comparison in the full code generator to use CompareIC instead of the CompareStub to record the types. This also implements the patching in the full code generator where the inlined smi code is de-activated by default to call the CompareIC once and then activating the inlined smi code by patching the code.

Fixed the smi comparison in the ICCompareStub.

Fixed ToBooleanStub to ensure that the scratch register used is not the input. Use r9 as default as that will never be input with Crankshaft.

Implemented lithium instruction CmpTAndBranch.

Make sure that the lithium instruction CmpID have operands in registrers as the current optimized code expects that.
