7a82ba0510 Fix a couple of minor problems. Because PHI nodes can use themselves, this 
could cause infinite loops.  Also, getUnderlyingObject can return null

04b7593546 Implement mod/ref analysis for a trivial case where locals don't escape. 
This comes up when you have a local array on the stack and you never pass
the address of elements around.

c760d647c6 Get rid of the abort in PhyRegAlloc::finishSavingState(). 
Make an explicit call to it from runOnFunction() if we know we're supposed to
write into the global. This is lame (esp. the const_cast), but it solves
the problem.

cf68bd5fc1 In PhyRegAlloc::saveState(), dump Arguments' saved-state, and try to 
make the output more compact.

Divorce state-saving from the doFinalization method; for some reason it's not
getting called when I want it to, at Reoptimizer time. Put the guts in
PhyRegAlloc::finishSavingState(). Put an abort() in it so that I can be really
really sure that it's getting called.

Update comments.

d1b3679214 Move all the SaveState options and stuff inton one spot at the top of the file. 
De-constify SaveStateToModule; we have to set both it and SaveRegAllocState
explicitly in the reoptimizer.
Make SaveRegAllocState an 'external location' option.
