Jason McDonald 924d810dbd Avoid using QSKIP in lieu of compile-time checks 
QSKIP is intended to be used to skip test functions that are found at
run-time to be inapplicable or unsafe.  If a test function can be
determined to be inapplicable at compile-time, the entire test function
should be omitted instead of replacing the body of the test function
with a QSKIP, which only serves to slow down test runs and to inflate
test run-rates with empty, inapplicable tests.
