Commit e2416566 by Derek Mauro Committed by Copybara-Service
Options

Add the ability to turn on warnings that get disabled in tests 

in GCC and LLVM build configs

This was accomplished by adding GccStyleFilterAndCombine() in copts.py

Previously, if we had a default warning of the form -Wwarning, adding
-Wno-warning to the list of test warnings would just add conflicting
flags. We now filter -Wwarning if -Wno-warning is added to the test warnings.
