#1082 CPD performance issue on larger projects

Milestone: PMD-5.0.4

Module: CPD

Priority: 2-Critical

When running CPD on a large code base, it takes much longer to run starting with version 5.0.1. Previously, with version 5.0.0 and earlier, it took a few seconds to run (on a project with 200k LOC). Starting with version 5.0.1 and through the latest version, it's taking a couple minutes. I ran VisualVM profiler while CPD was running and it looks like most of the time is spent in JavaTokenizer.inDiscardingState and JavaTokenizer.tokenize methods.
