new testcase with O0

Here a reduced test case that raises this ICE with current svn version:
$ gcc -O0 -S -fgnu-tm ICE_ipa_tm_propagate_irr.i 
ICE_ipa_tm_propagate_irr.i: In function ‘readLoop’:
ICE_ipa_tm_propagate_irr.i:23:1: internal compiler error: in
ipa_tm_decrement_clone_counts, at trans-mem.c:3763
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

and raises this ICE with Andrew's patch (tm2.patch)
gcc -O0 -S -fgnu-tm ICE_ipa_tm_propagate_irr.i
ICE_ipa_tm_propagate_irr.i: In function ‘readLoop’:
ICE_ipa_tm_propagate_irr.i:23:1: internal compiler error: in
