Sure, performance tests don't use it, actually functional testing also have
choice, It only take effective while launching dts with '--asan'

Asan failures sometimes cause cases/suites failure, sometimes not. Some guys
would care about the cases/suites failure, and some guys would care about the
asan failure. That's why we adding a new result file for asan, but not replace
the current one.

Agree that, also we need a guides.

I am considering to add more sanitizers easily for users, so we are going have
something as following.

filter_bounds=LeakSanitizer:SUMMARY,AddressSanitizer:SUMMARY

It separates different sanitizers by comma, and pair start and end by colon.
