Add frozen_string_literal: false for all files

2015-12-16T05:07:31+00:00

When you change this to true, you may need to add more tests.

compile optimized case dispatch for nil/true/false

2015-12-08T01:46:45+00:00

nil/true/false are special literals just like floats, integers,
literal strings, and symbols.  Optimize when statements with
them by using a jump table, too.
