[CodeGen] Enable the complex-math test for arm

[phosek]

Summary

This test wasn't running due to a missing : after the RUN statement.
Enabling this test revealed that it's actually broken.

LGTM. Thanks for the fix. My apologies for missing that at the time, it looks like a cut and paste error on my part.
