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.

For now this trick is only done to objects in new space, see comments
for reasons.

Previously we marked compare operations that occurred as for loop
conditions so as to avoid inlining the floating-point code for them.
Begin marking all expressions that occur as any loop condition
(because they are never dead code).

This change adds a data-flow pass to statically determine
if a variable contains a primitive type.

It requires building the flow graph and computing reaching
definitions as pre-requisites. The analysis annotates all
VariableProxy nodes with the result.

Modify FastD2I to use static_cast instead of lrint(). Benchmarks show that it's much faster this way.

incorrect. v8::Script::Compile returns wrapped JSFunction,
not SharedFunctionInfo.

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.

This is for the case of Linux, where sampling is done using SIGPROF
signal handler which is executed in the context of an interrupted
thread. In this case, my previous implementation with TLS doesn't

This change adds the option to peel off the first iteration of inner loops.

Loop peeling is off by default and can enabled by a flag. It also requires building a flow graph.

As part of this I added the possibility to clone AST nodes.
