(https://github.com/ruby/irb/pull/429)
* Create a base TestIRB::TestCase class
* Save/restore encodings for tests that initializes InputMethod classes
Because `RelineInputMethod#initializes` calls `set_encoding`, which
changes stdio/out/err and Encoding's default encoding values, we need to
make sure any test that directly or indirectly (e.g. through Context)
initializes `RelineInputMethod` restores encodings.
`ReadlineInputMethod` also changes encodings but currently no tests
cover it.
* Remove unnecessary TestHelper module
Since we now have a base TestCase, without_rdoc can just live there.
