Max Moroz f81476ca75 [infra] Add post build checks for catching and reporting bad builds + add test projects. (#754) 
* [WIP] Add post build checks for catching and reporting bad builds + test projects.

* Move all type of issues into a single project. Tested all sanitizers.

* First version of the script for performing bad build checks. Still not ready to commit.\

* Added a valid example that should pass all the checks + fixed instrumentation check.

* Use SIGTERM and the handler calling _exit(0) for the startup crash case.

* Small fixes.

* Ignore startup_crash check_for fuzzing engines other than libFuzzer.

* Use "local" for local variables in the script, fix container name.

* Add COPY step for bad_build_check into base-runner Dockerfile.

* Make bad_build_check temporary noop unless EXPERIMENTAL_BAD_BUILD_CHECK is set to 1.

* Temporary remove test binaries step.

* Remove empty line.

* Remove unnecessary env variable.

Max Moroz 3cee68fa11 [infra] Remove "null" check from UBSan options. (#674) 
There is not much value for us from this particular check:
- UBSan's "null" reports leading to real crashes are reported with ASan as well.
- Potential null references are not real crashes and might be considered
  as false positives, though it seems to be UB as per the standard.
