I also realized my previous patch would allocate a new UTF_8 on every
invocation of the
innermost lookup (oops!).
Avoiding the toLower means the non-standard Charset.forName("utf-8")
will take a
slower path (it still works, of course), but removes a few bytecode from
startup. We still need to key on the lower-case name in the cache for now:

Right, this is unfortunate. We could change the
sun.nio.cs.StandardCharsets constants to
something else as they are encapsulated.
