This patch removes dead patterns for incscc and decscc from thumb2.md.

It's a cleanup after this patch:
http://gcc.gnu.org/ml/gcc-patches/2013-01/msg00955.html
which removed incscc and decscc expanders and the corresponding patterns
from arm.md, but not from thumb2.md.

No regression on qemu for arm-none-eabi cortex-a15 thumb.

Ok for trunk?

Thanks,
Greta
