<pre>
    The wmma.py test is one of the slowest tests in the whole test suite.  On my system, it takes 23.40s to run (nearly all the other tests take less than 2s).  I was looking at the test and I noticed a few things that might be bugs:

- The test uses a lot of -DAG suffixes, is this really necessary?
- It's not clear what some of the patterns, like `PTX71MMA-DAG: mma.m16n8k16.row.col{{.*}}.u8.u8` are supposed to match.  It looks to me like it might be matching things that aren't intended.

@Artem-B would you be able to take a look and see if there is anything that could be done to speed up the test?
