COVERAGE__ and introduce coverage.so instead. How to measure
coverage: (1) require "coverage.so", (2) require or load Ruby source
file, and (3) Coverage.result will return the same hash as COVERAGE__.
[ruby-dev:35324]
* thread.c (rb_enable_coverages): start coverage measurement by using
rb_add_event_hook.
* thread.c (rb_get_coverages): returns current results of coverage
measurement.
* include/ruby/intern.h: add prototype for above two functions.
* vm_core.h, vm.c: add field of coverages to rb_vm_t.
* insns.def (trace): remove special handling for COVERAGE__.
* iseq.c (prepare_iseq_build): switch COVERAGE__ to
rb_get_coverages().
* parse.y (coverage): ditto.
* thread.c (clear_coverage): ditto.
* lib/coverage.rb: use coverage.so instead of COVERAGE__.

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.
