1b833ff35e Additional minor cleanup regarding CallWrapper: Use the null object pattern.

5197bff4f2 Unified CallWrapper and PostCallGenerator classes, the former is a 
generalization of the latter. This makes CallWrapper architecture-independant,
so it can be pulled up into assembler.h, nuking 3 copy-n-paste classes. Only a
small improvement, but nevertheless...

00bc2db28f ARM: Support hardfloat in SCons build and make it a build time setting 
Add option armeabi to the SCons build for selecting the floating point variant to use. Also add externally defined CCFLAGS environment for all targets. Run test.py with option -S armeabi=hardfloat to test with hardfloat enabled.

Make selecting hardfloat EABI variant a build-time option instead of a runtime option.

Add a simple check of the EABI variant during V8 initialization to exit if the compilation was not configured correctly. The reason for this is that GCC does not provide a compile time symbol defining the EABI variant. This check is not fool-proof as it cannot check the compilation configuration used for the snapshot if any.

Ensure that there is always enough bytes between consequtive calls in optimized code to write a call instruction at the return points without overlapping.

Add a call to deoptimize all functions after running tests with --stress-opt. This will catch some issues with functions which cannot be forcefully deoptimized. Some of the tests failed on ARM with that change without the rest of the changes in this change.

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.

da03f275d2 ARM: Implement DoDivI in the lithium code generator. 
This change provides fast code for a few special cases and calls the GenericBinaryOpStub for the rest.

It also changes the register allocation in the generation of lithium instructions to use fixed registers that are compatible with the generic stub. This allocation can be change once we use a more flexible implementation.

Finally, this change provides infrastructure to save double registers at safepoints, which is need to call the stub in deferred code.
