ede938b425 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.

b3f9f99ff2 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.

a3ed4044b0 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.

a55628694a Implement folding explicit load instructions into binary operations. For a 
testcase like this:

int %test(int* %P, int %A) {
        %Pv = load int* %P
        %B = add int %A, %Pv
        ret int %B
}

We now generate:
test:
        mov %ECX, DWORD PTR [%ESP + 4]
        mov %EAX, DWORD PTR [%ESP + 8]
        add %EAX, DWORD PTR [%ECX]
        ret

Instead of:
test:
        mov %EAX, DWORD PTR [%ESP + 4]
        mov %ECX, DWORD PTR [%ESP + 8]
        mov %EAX, DWORD PTR [%EAX]
        add %EAX, %ECX
        ret

... saving one instruction, and often a register.  Note that there are a lot
of other instructions that could use this, but they aren't handled.  I'm not
really interested in adding them, but mul/div and all of the FP instructions
could be supported as well if someone wanted to add them.
