yui-knk c0ffccf722 parse.y: Fix the locations of NODE in percent strings
* parse.y (parser_yylex): token_flush before
    calling parse_string. Without token_flush
    the first locations of NODE in percent strings
    are set to the location of %.

  e.g. The locations of NODE_STR is fixed:

  ```
  %w[a b]
  ```

  * Before

  ```
  NODE_STR (line: 1, first_lineno: 1, first_column: 0, last_lineno: 1, last_column: 4) ("a")
  NODE_STR (line: 1, first_lineno: 1, first_column: 0, last_lineno: 1, last_column: 6) ("b")
  ```

  * After

  ```
  NODE_STR (line: 1, first_lineno: 1, first_column: 3, last_lineno: 1, last_column: 4) ("a")
  NODE_STR (line: 1, first_lineno: 1, first_column: 5, last_lineno: 1, last_column: 6) ("b")
  ```

yui-knk 1bf50894ef parse.y: Set the last location of NODE_ARRAY in %w
* parse.y: list_append uses the locations
    of the second argument. So we should set the

  e.g. The locations of NODE_ARRAY is fixed:

  ```
  %w[a b]

SHF_COMPRESSED was not defined until glibc 2.22, and there are

defined.

Perhaps it is safe to define SHF_COMPRESSED to (1 << 11) ourselves,
too, since ELF should be a standardized format.

yui-knk f26cce0bba NODE_CALL is not passed to node_assign_gen
* parse.y (node_assign_gen): NODE_CALL is not passed to
  node_assign_gen. NODE_CALL is not assignable. Assignable
  method call (array set and attr set) is represented by NODE_ATTRASGN.

yui-knk 114fc2201c Fix location of assignable nodes
* parse.y (node_assign_gen): NODE_ATTRASGN is created
  before rhs is created. It is needed to set location
  after rhs is created to rhs range be included to the
  location of NODE_ATTRASGN.

  e.g. The locations of NODE_ATTRASGN is fixed:

  ```
  a[1] = 2
  ```

  * Before

  ```
  NODE_ATTRASGN (line: 1, first_lineno: 1, first_column: 0, last_lineno: 1, last_column: 4)
  ```

  * After

  ```
  NODE_ATTRASGN (line: 1, first_lineno: 1, first_column: 0, last_lineno: 1, last_column: 8)
  ```

ko1 d2bb08ecf0 remove a wrong assertion.
* iseq.c (rb_iseq_trace_set): remove a wrong assertion.
  This assertion checked `insn` is `trace_` prefix instruction
  but threaded code `insn` is original code.
