Store last location of a node on RNode

* node.c (rb_node_init): Initialize last location with 0.

* node.h (struct rb_code_range_struct): Define a structure
  which contains first location and last location of a node.
* node.h (struct RNode): Use rb_code_range_t to store last
  location of a node.
* node.h (nd_column, nd_set_column, nd_lineno, nd_set_lineno):
  Follow-up the change of struct RNode.
* node.h (nd_last_column, nd_set_last_column, nd_last_lineno, nd_set_last_lineno):
  Define getter/setter macros for last location of RNode.

* parse.y : Set last location of tokens.

Thanks to Yusuke Endoh (mame) for design of data structures.
