Subject: * variable.c (rb_class_path_no_cache): add a function to get the
 class   path without caching the computed path. Some classes are frozen, and 
  will raise an exception without this.

* probes.d (cmethod-entry, cmethod-return): separate cmethods from
  regular methods to match set trace func.

* probes_helper.h: refactor macros.  Fix probes to avoid calling
  #inspect when profiling.

* insns.def: update for use with new macros.

* vm_eval.c: ditto

* vm_insnhelper.c: ditto

* test/dtrace/test_singleton_function.rb: fix test for new output.

* test/dtrace/test_cmethod.rb: test the cmethod probes.
