[PATCH, GCC/ARM] Fix MVE scalar shift tests

[Mihail Ionescu]

Hi,

This patch fixes the scalar shifts tests added in:
https://gcc.gnu.org/ml/gcc-patches/2019-11/msg01195.html
https://gcc.gnu.org/ml/gcc-patches/2019-11/msg01196.html
By adding mthumb and ensuring that the target supports
thumb2 instructions.


*** gcc/testsuite/ChangeLog ***

2020-01-20  Mihail-Calin Ionescu  <mihail.ione...@arm.com>

        * gcc/testsuite/gcc.target/arm/armv8_1m-shift-imm-1.c: Add mthumb and 
target check.
        * gcc/testsuite/gcc.target/arm/armv8_1m-shift-reg-1.c: Likewise.


Is this ok for trunk?


Regards,
Mihail
