Should be fixed now:

r133288 | echristo | 2011-06-17 13:41:29 -0700 (Fri, 17 Jun 2011) | 6 lines

Lower multiply with overflow checking to __mulo<mode>
calls if we haven't been able to lower them any
other way.

Fixes rdar://9090077 and rdar://9210061

r133318 | echristo | 2011-06-17 17:09:57 -0700 (Fri, 17 Jun 2011) | 6 lines

Fix UMULO support for 2x register width to allow the full
range without a libcall to a new mulo<mode> libcall
that we'd have to create.

Finishes the rest of rdar://9090077 and rdar://9210061
