Yusuke Endoh 2fed5f0ad8 lib/racc/statetransitiontable.rb: Make the racc output stable
Racc calls `Array#sort!` to build a state transition table. As
`Array#sort!` is not a stable sort, the output may differ depending upon
the environment.

This changeset makes the sort stable manually, and updates all
expectation files.
