1b1a8731c0 Use the asmprinter to find out what the preferred alignment of a global is. 
This patch speeds up 172.mgrid from 31.81s to 11.39s on darwin/ppc.
Many many thanks to Nate for tracking down the root cause of the issue.

219d559824 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.

c126397a69 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

fafff9ba1d Make BB and CPI labels use the function number, not the function name as a 
uniquing id.  This makes things happy when the function name is quoted,
preventing labels like LBB"foo"_2.
