[PATCH, SMS] Support instructions with REG_INC_NOTE

[Revital Eres <revital dot eres at linaro dot org>]

Hello,

The attached patch extends the current implementation to analyze
instructions with REG_INC_NOTE.

Tested on ppc64-redhat-linux (bootstrap and regtest) SPU (only regtest)
and arm-linux-gnueabi (bootstrap c and regtest) configured with
--with-arch=armv7-a --with-mode=thumb.

OK for mainline?

Thanks,
Revital
