[Bug math/15359] Inaccurate cos for IBM long double

The implementation isn't broken, it's just inaccurate.

What problems do we have leaving the test in place and using a large ulp value
for IBM long double?

I noticed that Joseph also said he would like to disable cpow once we switch to
accurate ulps since the error in cpow is going to be a huge number of ulps.

Is this just a policy issue? That we disable tests if the ulp values are too
high?
