3afbf69f53 Relax verification of JSFunction result caches. 
As invocation of a functin may trigger GC and hence clear all the caches,
it's hard to ensure previous invariants.

Current invariant is both a key and a value should be the holes or not holes.

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.

8805509f28 Wrap external pointers more carefully. 
On 32-bit platforms any pointer with 0 as LSB can be wrapped into Smi.  However, on 64-bit
platforms it's currently not the case as x64 Smis must have 0s in lower 32 bit word.
Even worse, macroassembler Move instruction will try to fetch integer value from Smi
and will shift by 32 bits to the right rendering stored pointer incorrect.

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.
