A bisection has identified this as a regression on 4.4 branch triggered by
r147081, the fix for PR39914. The same change was committed to trunk too, but
for some reason doesn't trigger the ICE there.

Trunk also ICEd on this test case for a while, but that was fixed by r147282,
one of several fixes to fwprop/df-problems.

gcc-4.5-20100204 ICEs with -O1 -fno-forward-propagate -fPIC -mthumb on the
original test case. So r147282, which enabled fwprop at -O1, merely masked the
problem.
