This adds sanitizer-coverage compilation, test-runner features and post processing. Sanitizer coverage is expected to be used together with asan. During test runner execution, the produced sancov files are disambiguated and match the pattern: <executable name>.test.<test id>.sancov. Two additional scripts are added for merging raw sancov files and for generating json data containing all instrumented lines + all covered lines from merged sancov files. Both scripts use multiprocessing for speed. The json data will later be uploaded to google storage for further use, e.g. to show coverage data in rietveld.
