Log:
Enable debug info at -O.  I've fixed a lot of
bugs where -g affects optimization recently; there
are currently no such cases in the llvm testsuite or
a substantial amount of other code on Darwin, which
seems sufficient to turn it on.  Woot.  I make
no claims about the quality of the generated debug
info.

Any cases where you see -g affecting optimization can
now usefully be reported as bugs.  TEST=ipodbgopt should
test this in the llvm testsuite.
