73fe82426f Strengthen requirements for fixed registers at calls. 
Already done on ia-32. This change is for x64 and ARM.
We now always require fixed input registers at calls to
avoid overlap with temp registers.

This fixes the affected instructions on ARM.

c0fd053982 Fix a representation change bug in the Hydrogen graph construction. 
We could try to treat an HPhi as an HInstruction because the code did
not properly handle the case of a phi in a block with itself as one of
the predecessors.

Whenever we use a fixed temp at a call that can eagerly deopt we
now allow fixed register exclusively to avoid any overlap.

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.

Compare JSObjects by identity immediately.

When invoking EQUALS JS builtin, 1st argument is passed as a receiver and
if it's a global object, it gets overwritten with global proxy object and
thus one gets incorrect results.

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.

52cfd6ab16 Fixed a number of issues on x64 crankshaft port: 
- Don't use SmiSub when overflow can occur. It asserts that overflow
  does not happen.

- Actually use CompareICs and signal to crankshaft whether or not smi
  code was inlined.

- Fix bug in CmpI where 64 bits were compared instead of 32 bits.

- Implement Throw, DeferredStackCheck, StoreKeyedFastElement in
  lithium backend.
