Support renaming an existing value of an enum type.
Not much to be said about this patch: it does what it says on the tin.
In passing, rename AlterEnumStmt.skipIfExists to skipIfNewValExists
to clarify what it actually does. In the discussion of this patch
we considered supporting other similar options, such as IF EXISTS
on the type as a whole or IF NOT EXISTS on the target name. This
patch doesn't actually add any such feature, but it might happen later.
