arm_thumb2_ok says that the target generates thumb2 code with -thumb.
arm_thumb2 says that with no additional options it generates thumb2
code.
The test could use either "dg-require-effective-target arm_thumb2" or
"dg-require-effective-target arm_thumb2_ok" plus "dg-options "-mthumb";
for either of those the checks on dg-final aren't necessary.
