Remove warnings from terminal when compiling the test runner.

A fix for the test runner that patches most of the warnings
that are reported in the terminal when compiling the test runner.
Some warnings were suppressed as it was too time-consuming or
there were impacts to other parts of the test runner when they
were fixed.
