v8/tools/testrunner/standard_runner.py
Tamer Tas 5b957fa169 [testrunner] explain how the testrunner progress percentage is calculated 
Progress indicator calculates the percentage using the estimated amount of
tests.

When base tests produce more tests or when testrunner filters some tests, the
percentage terminates over 100% or under it.

This CL adds an informative message about how the percentage behaves.
