gc.c: expose GC.stat() to C-api via rb_gc_stat()
* include/ruby/intern.h: add rb_gc_stat() for access to GC.stat variables from c-api * gc.c (rb_gc_stat): new c-api method. accepts either VALUE hash like GC.stat, or VALUE symbol key and returns size_t directly. the second form is useful to avoid allocations, i.e. for usage inside INTERNAL_EVENT_GC tracepoints. * gc.c (gc_stat): add GC.stat(:key) to return single value instead of hash * gc.c (gc_stat_internal): helper method to retrieve single or all stat values * test/ruby/test_gc.rb (class TestGc): test for new behavior * NEWS: note about this new api git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@44005 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
