The following continue to be ignored:
* Generic.Arrays.DisallowLongArraySyntax.Found, because I'm not sure
Scribunto is ready to abandon old version support in master.
* MediaWiki.ControlStructures.AssignmentInControlStructures.AssignmentInControlStructures,
because it's overly strict for its purpose.
Squiz.Classes.ValidClassName.NotCamelCaps isn't ignored globally, we
just ignore it explicitly every place it's needed.

The pure-Lua ustring pattern matching functions short-circuit to the
much faster string library when the pattern would match the same against
the raw bytes.
A pattern like "[^a-z]" can match a partial UTF-8 character when applied
bytewise, and so must be detected as unsafe.
Let's also directly test the pure-Lua module, instead of me having to
comment out lines in Scribunto_LuaUstringLibrary::register() whenever I
want to test them.
