testsuite/arm: add missing -mthumb to several tests

Some tests force -mcpu=cortex-mXX but do not add -mthumb, causing
errors if GCC is not configured to default to Thumb code
(--with-mode=thumb):
cc1: error: target CPU does not support ARM mode

This patch adds -mthumb where relevant.

2020-11-23  Christophe Lyon  <christophe.lyon@linaro.org>
