* Add coverage measurement constant COVERAGE__. This constant is not
for casual use. Usage: (1) assign {} to COVERAGE__, (2) require or load Ruby source file, and (3) COVERAGE__["sourcefilepath"] will return an array whose elements represent number of executions per line of source code. * vm_core.h: add field of coverage array to iseq. * iseq.c (prepare_iseq_build): ditto. * insns.def (trace): update coverage array. * parse.y (coverage): create and initialize coverage array. * compile.h (ADD_TRACE): add trace instruction to update covearge array. * thread.c (clear_coverage): delete coverage array when forking. Otherwise, double count of coverage may occur. * lib/coverage.rb: sample coverage measurement tool. * error.c: distinguish explicitly between parse_in_eval and mild_compile_error. * load.c: ditto. * vm_eval.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@17781 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
