* string.c (rb_fstring, fstr_update_callback): simply delete garbage
  key first.
  Garbage keys can be swept by lazy sweeping invoked by creating new
  fstring.  So that simply do:
  (1) delete garbage key and return `fstr_update_callback' immediately
  (2) try again `fstr_update_callback()' to create a new fstr.
  This bug can be cause memory corruption, reported by
  http://u64.rubyci.org/~chkbuild/ruby-trunk/log/20140821T220302Z.fail.html.gz

rb_iseq_location_t: change first_lineno type to VALUE

Nearly all current uses of iseq->location.first_lineno are as a
VALUE, not a size_t.  The only exception was the experimental

* iseq.c (rb_iseq_build_for_ruby2cext): update based on argument
