Add better comments, including a better head-of-file comment.
Prune #includes.
Fix a FIXME that Chris put here by using doInitialization().
Use DEBUG() to print out debug msgs.
Give names to basic blocks inserted by this pass.
Expand tabs.
Use InsertProfilingInitCall() from ProfilingUtils to insert the initialize call.

in the size calculation.

This is not something you want to see:
Loop Unroll: F[main] Loop %no_exit Loop Size = 2 Trip Count = 2147483648 - UNROLLING!

The problem was that 2*2147483648 == 0.

Now we get:
Loop Unroll: F[main] Loop %no_exit Loop Size = 2 Trip Count = 2147483648 - TOO LARGE: 4294967296>100

Thanks to some anonymous person playing with the demo page that repeatedly
caused zion to go into swapping land.  That's one way to ensure you'll get
a quick bugfix.  :)

and passing a null pointer into a function.

For this testcase:

void %test(int** %X) {
  store int* null, int** %X
  call void %test(int** null)
  ret void
}

we now generate this:

test:
        sub %ESP, 12
        mov %EAX, DWORD PTR [%ESP + 16]
        mov DWORD PTR [%EAX], 0
        mov DWORD PTR [%ESP], 0
        call test
        add %ESP, 12
        ret

instead of this:

test:
        sub %ESP, 12
        mov %EAX, DWORD PTR [%ESP + 16]
        mov %ECX, 0
        mov DWORD PTR [%EAX], %ECX
        mov %EAX, 0
        mov DWORD PTR [%ESP], %EAX
        call test
        add %ESP, 12
        ret
