Subject: [PATCH] Enable config=sanitize in Travis CI

This commit changes sanitize configuration to fail on the first error
and ignore floating-point division and overflow "errors" that trigger
when we test the corresponding functionality. This makes it possible to
run this on all commits - if new UB or memory safety issues are introduced,
asan/ubsan will catch them.
