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.

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.

De-constify SaveStateToModule; we have to set both it and SaveRegAllocState
explicitly in the reoptimizer.
Make SaveRegAllocState an 'external location' option.

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.

Emit RETL instruction to return instead of funny JMPL.
Fix indentation.

llvm-svn: 12186

Add RET, RETL.  Rename SAVE, RESTORE & JMPL for consistency.

been using the default target data layout object to lower malloc instructions,
causing us to allocate more memory than we needed!  This could improve the
performance of the CBE generated code substantially!
