[CLOV-1328] as a Clover developer I'd like to use the latest version of ANTLR

Feedback Policy:

Our product teams collect and evaluate feedback from a number of different sources. To learn more about how we use customer feedback in the planning process, check out our new feature policy.

Clover uses ANTLR 2.x currently which is few light-years from the latest version, which is ANTLR 4.x. Upgrade to the latest ANTLR library version.

check ANTLR 4.x license (it's different from 2.x) whether we can actually use it; if not - try to use 3.x, if possible
check if there's any Java grammar (the best for Java 8) available for Antlr 4
estimate whether it's better to use completely new grammar file and embed clover stuff there or to upgrade our existing grammar file from 2.x to 4.x
- watch out for our custom extensions like unicode escape sequence handling, annotations etc
