* probes.d: add DTrace probe declarations. [ruby-core:27448]

* array.c (empty_ary_alloc, ary_new): added array create DTrace probe.

* compile.c (rb_insns_name): allowing DTrace probes to access
  instruction sequence name.

* Makefile.in: translate probes.d file to appropriate header file.

* common.mk: declare dependencies on the DTrace header.

* configure.in: add a test for existence of DTrace.

* eval.c (setup_exception): add a probe for when an exception is
  raised.

* gc.c: Add DTrace probes for mark begin and end, and sweep begin and
  end.

* hash.c (empty_hash_alloc): Add a probe for hash allocation.

* insns.def: Add probes for function entry and return.

* internal.h: function declaration for compile.c change.

* load.c (rb_f_load): add probes for `load` entry and exit, require
  entry and exit, and wrapping search_required for load path search.

* object.c (rb_obj_alloc): added a probe for general object creation.

* parse.y (yycompile0): added a probe around parse and compile phase.

* string.c (empty_str_alloc, str_new): DTrace probes for string
  allocation.

* test/dtrace/*: tests for DTrace probes.

* vm.c (vm_invoke_proc): add probes for function return on exception
  raise, hash create, and instruction sequence execution.

* vm_core.h: add probe declarations for function entry and exit.

* vm_dump.c: add probes header file.

* vm_eval.c (vm_call0_cfunc, vm_call0_cfunc_with_frame): add probe on
  function entry and return.

* vm_exec.c: expose instruction number to instruction name function.

* vm_insnshelper.c: add function entry and exit probes for cfunc
  methods.

* vm_insnhelper.h: vm usage information is always collected, so
  uncomment the functions.

* configure.in (isinf, isnan): isinf() and isnan() are macros on
  DragonFly which cannot be found by AC_REPLACE_FUNCS().  This
  workaround enforces the fact that they exist on DragonFly.

* vm_core.h (rb_call_info_t::refinements), compile.c (new_callinfo),
  vm_insnhelper.c (vm_search_method): revert r37616 because it's too
  slow.  [ruby-dev:46477]

* test/ruby/test_refinement.rb (test_inline_method_cache): skip
  the test until the bug is fixed efficiently.
