Summary: SelectionDAG crashes on optnone function after r308025

reduced IR test case
After r308025, SelectionDAG crashes while compiling the file:
https://github.com/xiph/speex/blob/master/libspeex/testenc.c
(Possibly some older version of it, I haven't checked...)
I'm attaching a minimized test case that pretty clearly shows the bug. It seems
specific to O0 (optnone attribute is applied).
Because this is blocking even unoptimized builds I'm going to revert the patch
while it gets investigated.
