Doug Gregor 449aa2f6b4 Mark conformances as "used" when the GenericSignatureBuilder needs them.

When the type checker forms a GenericSignatureBuilder to process
requirements, the GSB may look up concrete conformances. Route such
requests through TypeChecker::conformsToProtocol() so they can be
marked as used. This fixes multi-file scenarios where conformances
from another file might be used only in a generic signature in the
primary file, e.g., rdar://problem/31759258.
