Did anything else change?  The latest binutils has better debug support, so I
could imagine us ending up with some longer compiler times as a result -- there
has to be more than just that here, though.

Aside from that we have had a ton of vector codegen go in over the last few
months, but this is a pretty huge increase so I agree it's worrisome.  I'm
adding Vineet to the CC list, as he's been doing some SPEC runs.  I don't think
we've had any major runtime regressions, but looks like dwarf2out.cc times have
crept up a bit which is also worrisome.

Also what exactly are you timing?  Native boostraps on QEMU?
