* vm_core.h (rb_iseq_t): move flip_cnt from struct iseq_compile_data,
  because it has same life span as enclosing iseq.  [Bug #7671]

* compile.c (iseq_compile_each): count flip-flop state in local iseq
  not in each iseqs, so that the keys can be other than hidden
  strings.  [ruby-core:47253] [Bug #6899]
* vm_insnhelper.c (lep_svar_get, lep_svar_set, vm_getspecial): store
  flip-flop states in an array instead of a hash.
* iseq.c (set_relation): main iseq also can has local scope.

  Fixnum because they are pushed into Array in a compiler.
  [Bug #7502]
* test/ruby/test_objectspace.rb: add a test of this issue.

* iseq.c: add following two methods.
* ISeq#line_trace_all returns all line traces (line numbers)
* ISeq#line_trace_specify(pos, set) set `pos'th line event to
  specified_line event (if set is true).
  These features are introduced for debuggers (mainly to make
  breakpoint).
* iseq.h: add decl. of C APIs.
* test/ruby/test_iseq.rb: add tests.
* vm_trace.c: add `specified_line' event.
* include/ruby/ruby.h: ditto.

* compile.c (defined_expr), insns.def (defined): share single frozen
  strings.  [EXPERIMENTAL] [ruby-core:47558][Feature #7035]
* iseq.c (rb_iseq_defined_string): make expression strings.

  to solve an issue reported at [ruby-dev:44413] [Ruby 1.9 - Bug #5217].
  Before this fix, each instruction has an information including
  line number (iseq::iseq_insn_info_table).  Instead of this data
  structure, recording only line number changing places
  (iseq::iseq_line_info_table).
  The order of entries in iseq_line_info_table is ascending order of
  iseq_line_info_table_entry::position.  You can get a line number
  by an iseq and a program counter with this data structure.
  This fix reduces memory consumption of iseq (bytecode).
  On my measurement, a rails application consumes 21.8MB for
  iseq with this fix on the 32bit CPU.  Without this fix, it
  consumes 24.7MB for iseq [ruby-dev:44415].
* proc.c: ditto.
* vm_insnhelper.c: ditto.
* vm_method.c: ditto.
* vm.c (rb_vm_get_sourceline): change to use rb_iseq_line_no().

  Now it is declared in method.h with same const-ness to the
