compile.c: add a RUBY_EVENT_COVERAGE_LINE event for line coverage
2.5's line coverage measurement was about two times slower than 2.4 because of two reasons; (1) vm_trace uses rb_iseq_event_flags (which takes O(n) currently where n is the length of iseq) to get an event type, and (2) RUBY_EVENT_LINE uses setjmp to call an event hook. This change adds a special event for line coverage, RUBY_EVENT_COVERAGE_LINE, and adds `tracecoverage` instructions where the event occurs in iseq. `tracecoverage` instruction calls an event hook without vm_trace. And, RUBY_EVENT_COVERAGE_LINE is an internal event which does not use setjmp. This change also cancells lineno change due to the deletion of trace instructions [Feature #14104]. So fixes [Bug #14191]. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61350 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
