f5523ecc6a Split the virtual frame into heavy and light versions. 
The heavy version is for x86 and x64.  The light version
is for ARM and MIPS.  Remove the elements_ array from the
virtual frame in the light version.  More simplifications
to come, followed by light register allocation.

6a63910650 Re-apply "Inline floating point compare" 
This re-applies r4220 and r4233, which was reverted in r4254 due to a bug. This bug has now been fixed, with the only change being line 2884 changed from

  __ SmiTag(left_side->reg());

to

  __ SmiTag(operand->reg());

Added a regression test.

51495beb78 Store type information with constants. 
Instead of testing the value of a constant frame element to determine
the type we compute its type information at construction time.

This speeds up querying the type information during code generation.

This change also adds support for Integer32 constants and sets 
the type information accordingly.

3672624b45 Fix pop push optimization to work with partial snapshots (correct 
registration of external references in Proxy objects).
I moved the declaration of the two functions to stub-cache.h
because with all the types they use it's hard to declare them
anywhere else.  But the actual definition is still in runtime.cc
near to the place where they are used.

65115c2857 Mark all loop conditions. 
Previously we marked compare operations that occurred as for loop
conditions so as to avoid inlining the floating-point code for them.

9240342ad6 Inline floating point compare 
Inline floating point compare instead of calling the stub when the following conditions are met:
  * Code is in a loop
  * Compare is not a for loop condition
  * Compare is not an equal comparison

This inlined code handles heap number to heap number and heap number to smi compare. It can also handle smi to smi compare, but whenever there is a chance of comparing two smis the smi compare is inlined before the inlined floating point compare. Support for non SSE2 hardware is included.

A new set of variants of the compare stub without the floating point comparison code is called if the inline comapre fails due to the operands not beeing heap numbers or smis.

The virtual frame has been extended with a branch taking two live results to be carried through to the destination. This makes this change much simpler as the inlined code have two live results in registers and a number of bailouts.

CompareStub::GetName needs to be updated as well. I will do that as a separate change.

Also inlined equality check if both operands can't be NaN. This can only provide positive equals if it is the same object.
