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.

This instruction only depends on the prototype and the holder and can
completely ignore the receiver and its map.

This change also fixes a small bug on arm where a cell was loaded
instead of the prototype from new space.

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.

Each LInstruction is now a subclass of LTemplateInstruction<R, I, T>

where R is number of outputs, I number of inputs and T number of temps.

This change only actually uses the parameter I for input operands. 
Since the parameter T for temps is 0, it incurs no extra cost. 

A separate change will introduce using the temps parameter.

Rather than allocating a fresh gap move resolver for every parallel
move, use a single one per Lithium code generator.  This avoids always
reallocating the temporary zone-allocated lists used by the gap move
resolver.
