commit r15-5969-ge65b09d461d2a4f37fb55d6dcd2e94b1f444daea

More duplicates reported by genmatch
Here are a bit less obvious cases of duplicate, mostly of the
form (op (op:c @0 @1) (op:c @0 @1)) where it's enough to have
one :c to get all relevant cases.
* match.pd: Remove redundant :c, reported by genmatch as
duplicate patterns.
