George Balatsouras e112fc03eb [dfsan] Add -dfsan-fast-8-labels flag
This is only adding support to the dfsan instrumentation pass but not
to the runtime.

Added more RUN lines for testing: for each instrumentation test that
had a -dfsan-fast-16-labels invocation, a new invocation was added
using fast8.
