The order of making binding should be stack (frame) top to bottom.
[Bug #7635]
And also fix issue of collecting klass. Collecting klass is same
as TracePoint#defined_class.
(previous version, it returns T_ICLASS (internal objects).

This method is similart to `caller_locations' method for
specific method.
And fix to accept `level' and `n' parameters for `Thread#backtrace'
and `Thread#backtrace_locations'.
`caller' (and `caller_locations') do not return `caller' method
frame.
However, `Thread#backtrace' (and `Thread#backtrace_locations')
return `Thread#backtrace' method frame itself
if `Thread.current.backtrace' was called.

Before this commit:
`finish frame' was place holder which indicates that VM loop
needs to return function.
If a C method calls a Ruby methods (a method written by Ruby),
then VM loop will be (re-)invoked. When the Ruby method returns,
then also VM loop should be escaped. `finish frame' has only
one instruction `finish', which returns VM loop function.
VM loop function executes `finish' instruction, then VM loop
function returns itself.
With such mechanism, `leave' instruction (which returns one
frame from current scope) doesn't need to check that this `leave'
should also return from VM loop function.
Strictly, one branch can be removed from `leave' instructon.
Consideration:
However, pushing the `finish frame' needs costs because
it needs several memory accesses. The number of pushing
`finish frame' is greater than I had assumed. Of course,
pushing `finish frame' consumes additional control frame.
Moreover, recent processors has good branch prediction,
with which we can ignore such trivial checking.
After this commit:
Finally, I decide to remove `finish frame' and `finish'
instruction. Some parts of VM depend on `finish frame',
so the new frame flag VM_FRAME_FLAG_FINISH is introduced.
If this frame should escape from VM function loop, then
the result of VM_FRAME_TYPE_FINISH_P(cfp) is true.
`leave' instruction checks this flag every time.
I measured performance on it. However on my environments,
it improves some benchmarks and slows some benchmarks down.
Maybe it is because of C compiler optimization parameters.
I'll re-visit here if this cause problems.
* insns.def (leave, finish): remove finish instruction.
* vm.c, vm_eval.c, vm_exec.c, vm_backtrace.c, vm_dump.c:
apply above changes.

(1) rename rb_location_t to rb_iseq_location_t.
(2) rename field names of rb_iseq_location_t to adjust
RubyVM::Backtrace::Location methods.
(2-1) filename -> path
(2-2) filepath -> absolute_path
(2-3) basename -> base_label
(2-4) name -> label
(3) rename filed name rb_iseq_location_t#line_no to
rb_iseq_location_t#first_lineno to clear purpose of this field.
(4) The field names rb_binding_t#(filename|line_no) are also renamed
to rb_binding_t#(path|first_lineno).

(1) Class name: RubyVM::FrameInfo -> RubyVM::Backtrace::Location.
(2) Method name: RubyVM::FrameInfo.caller ->
Kernel.caller_locations.
(3) Instance methods of
RubyVM::FrameInfo (RubyVM::Backtrace::Location)
(3-1) name -> label
(3-2) basename -> base_label (basename is confusing with
File.basename)
(3-3) line_no -> lineno (We have already similar name
File#lineno, commented by kou [ruby-dev:45686]).
(3-4) filename -> path.
(3-5) filepath -> absolute_path.
(3-5) iseq -> removed (we will make other APIs to access iseq
and other information of frame for debugging).
* test/ruby/test_backtrace.rb: apply above changes.
And apply comment from kou [ruby-dev:45686].

is no longer included from vm.c). I hope this separation reduce
compile time of vm.c.
* internal.h: ditto.
* vm.c, vm_core.h, vm_dump.c, vm_eval.c: ditto.
* vm_eval.c: some functions (callee, etc) moved to vm_backtrace.c.
