This will allow to only load json data for the files under
review instead of the whole data set.
This will be called on the infra-side after all coverage
data has been merged.
Also fix a bunch of log lines.

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.
