Subject: [PATCH] Issue #16977, fix more compatibility issues with Python3.8.
xml.dom.minidom preserves attribute order in Python3.8 which causes
some test failures. Modified the order of attribute insertion to
ensure that tests run on both 3.8 & earlier versions. Modified the use
of officially removed time.clock with a conditional import in

Subject: [PATCH] Modify literal comparisons as per python3.8 guidelines
This is in regards to issue #16973, Python 3.8 beta raises a warning
when comparing with string, int literals using is. The .travis.yml compileall
command has been added another flag to error if the convention is not followed.
A dummy test has been added in utilities/tests, this must cause the travis
build to fail in 3.8. If it does as expected, it can be removed, else the
compileall command will have to be changed.
