[infra] Enable clange code coverage reports generation for local runs. (#1494) 
* [infra] Enable clange code coverage reports generation for local runs.

* Use runner image and move corpus management to the helper.py
.

* Clean up, delete unnecessary stuff, add comments.

* Run fuzz targets in parallel. Do not exit in case of an error.

* Address review feedback, except of the threading thing.

* Fix a typo.

* Use ThreadPool implementatino available in standard python2.7 package.

* Add dry run support + no corpus download option.

* Fix flags handling + add log output in case of an error.

* Append arguments for fuzz target instead of replacing them.

* Remove dry run functionality as it currently errors out after two runs.

* Fix some spacing in the code.

* Update documentation regarding new code coverage script.

[AFL] Improve builds of AFL package. (#1386) 
Improve builds of AFL package.

Silence trivial known compile warning when building afl-llvm-rt.o.c
Also, don't build afl-fuzz using CFLAGS and CXXFLAGS since we don't
actually want to sanitize it.

This should cause AFL to be built with -O3 -funroll-loops (the defaults) instead of -fsanitize=... -O1 and -ginline-tables-only.

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.
