c3b4338120 Fix the last crasher I've gotten a reproduction for in SROA. This one 
from the dragonegg build bots when we turned on the full version of the
pass. Included a much reduced test case for this pesky bug, despite
bugpoint's uncooperative behavior.

Also, I audited all the similar code I could find and didn't spot any
other cases where this mistake cropped up.

213f16cbf4 Fix getCommonType in a different way from the way I fixed it when 
working on FCA splitting. Instead of refusing to form a common type when
there are uses of a subsection of the alloca as well as a use of the
entire alloca, just skip the subsection uses and continue looking for
a whole-alloca use with a type that we can use.

This produces slightly prettier IR I think, and also fixes the other
failure in the test.

store this and use it to not emit long nops when the CPU is geode which

1fe8678a5d Add a major missing piece to the new SROA pass: aggressive splitting of 
FCAs. This is essential in order to promote allocas that are used in
struct returns by frontends like Clang. The FCA load would block the
rest of the pass from firing, resulting is significant regressions with
the bullet benchmark in the nightly test suite.

Thanks to Duncan for repeated discussions about how best to do this, and
to both him and Benjamin for review.

This appears to have blocked many places where the pass tries to fire,
and so I'm expect somewhat different results with this fix added.

As with the last big patch, I'm including a change to enable the SROA by
default *temporarily*. Ben is going to remove this as soon as the LNT
bots pick up the patch. I'm just trying to get a round of LNT numbers
from the stable machines in the lab.

NOTE: Four clang tests are expected to fail in the brief window where
this is enabled. Sorry for the noise!
