proposed fix

Hi, please review this proposed patch, which attempts to fix the validation
checks that wrongly reject good instructions.
I tested this by running the GAS test suite, and including the new test case I
included in the patch. Despite the original report mentioned addw/subw, I
wanted to extend the testing to other instructions as well, in order to ensure
that no other SP/PC-related operands were broken.
Please commit this for me if accepted, since I don't have write access.
