1ecabc5a6f trivial formatting improvement: don't insert extra blank lines between .comm
vars.

6b25a4e659 Added minimum Dwarf aranges. Cleaned up some section headers. Line number
support now works in gdb.

61138e28ff Applied some recommend changes from sabre. The dominate one beginning "let the
pass manager do it's thing."  Fixes crash when compiling -g files and suppresses
dwarf statements if no debug info is present.

constant offsets from statics into the address arithmetic.

d4562971b3 Fix a couple of the FIXMEs, thanks to suggestion from Chris. This allows
us to load and store vectors directly at a pointer (offset of zero) by
using r0 as the base register.  This also requires some asm printer work
to satisfy the darwin assembler.

For
void %foo(<4 x float> * %a) {
entry:
  %tmp1 = load <4 x float> * %a;
  %tmp2 = add <4 x float> %tmp1, %tmp1
  store <4 x float> %tmp2, <4 x float> *%a
  ret void
}

We now produce:
_foo:
        lvx v0, 0, r3
        vaddfp v0, v0, v0
        stvx v0, 0, r3
        blr

Instead of:
_foo:
        li r2, 0
        lvx v0, r2, r3
        vaddfp v0, v0, v0
        stvx v0, r2, r3
        blr

e1435b7831 Make BB and CPI labels use the function number, not the function name as a
