[coverage] Enable sanitizer coverage. 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.

Preparing v8 to use with python3 /tools There are now less that 400 days until the end of life of Python 2(aka _legacy_ Python) https://pythonclock.org/ . The code compatibility check for python2 and python3 used the following tools: futurize, flake8 You can see the reports here: https://travis-ci.com/bmsdave/v8/builds This CL was uploaded by git cl split.
