bbba0dbd61 Add a genuine unary minus instruction to Crankshaft. 
This change introduces an instruction for negation instead
of generating a multiplication with -1.

The code for x64 and ARM is not included in this change.

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).

bea46a2723 Port bug fixes to optimized Function.prototype.apply to ARM. 
There were a couple of bug fixes to this code on IA32 which have not yet
been ported to ARM.  They are: failure to correctly handle non-JSObject
receivers and failure to restore the context register after calling JS code.

ebebcae4c2 Allow esi to be an allocatable register on IA32. 
Make esi available to the register allocator rather than dedicating it
permanently to the context.

The context is still passed in register esi to JavaScript and to the runtime
as part of the calling convention.  Because some stubs might end up calling
JS or the runtime, it is also conservatively passed to stubs.

Roughly half the calls have been modified to use the context as an input
value in fixed register esi.  The other half are marked as calls or deferred
code so esi is spilled and can be explicitly set.

It is no longer necessary to restore the context to esi after a call that
might change it.

dc91c4218b Make optimized Function.prototype.apply safe for non-JSObject first arguments. 
If we have a property access of the form this.x, where the access site sees
the global object, we can specialize the IC stub so that it performs a map
check without first performing a heap object check.

Ensure that we do not get in JS code with a non-JSObject this value by
deoptimizing at Function.prototype.apply if the first argument is not a
JSObject.

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.
