[PATCH] D30035: Add const to function parameters

[David Blaikie via cfe-commits]

Adding const to pointed/referenced types doesn't usually help the compiler,
since they don't guarantee that the underlying object is const (nor that
any use can't involve const_casting away the constness and mutating the
value anyway).
