Protocol names end in "Type," "ible," or "able"

Mechanically add "Type" to the end of any protocol names that don't end
in "Type," "ible," or "able."  Also, drop "Type" from the end of any
associated type names, except for those of the *LiteralConvertible
protocols.

There are obvious improvements to make in some of these names, which can
be handled with separate commits.

Fixes <rdar://problem/17165920> Protocols `Integer` etc should get
uglier names.
