Travis: Enable additional sanitizer tests

- Re-purpose the non-SIMD test to test with MSan as well.
- Re-purpose the ASan test to test with UBSan as well.
- Use the default Travis build environment rather than specifying Ubuntu
  14.04.  I think I added 'dist: trusty' back when 14.04 was newer than
  the default, but now it's older than the default.
- Enable verbose output for any unit tests that fail (so we can see the
  sanitizer output.)
