[Bug target/44227] New: Invalid instruction generation in Thumb2 for tst instruction.

["ramana at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

CSiBe builds broke because of this change here to fix PR42879.

http://gcc.gnu.org/ml/gcc-cvs/2010-05/msg00263.html

Attached is a reduced testcase that shows the problem. The problem appears to
be due to incorrect generation of the tst instruction as a result of the
pattern added where the tst instruction appears to be generating a tst with
32767 which is an invalid immediate for the tst instruction in Thumb2 state.

Carrot, can you look at this further ?
