Summary:
This collapses all the "platform dependent" tests into a single travis
builder in an effort to reduce overall CI times. These builds currently
take a combined 21-23 minutes, but each one has to compile the library,
so combining them should yield some time savings (5-10 minutes).

Unfortunately the other builders don't duplicate work, so combining
them is unlikely to provide benefit.

Summary:
Travis provides a very low capability resource for testing and the
persistent cache tests are too aggressive. It causes the kernel to not have
enough time to do file-system meta data sync operation, causing open file
descriptors to increase and available space to decrease.

Summary: This diff avoids failing travis test when clang-format fails. We should keep the test green even if clang-format fails. It would be good to look at travis output for pull requests to make sure they're following the good code style. However, we broke travis test 3 times today because of formatting issues. We should keep travis test green if the only thing wrong is the formatting.
