Sema: Nuke NominalTypeDecl::markInvalidGenericSignature()

Browse Source 
This would just set the NominalTypeDecl's declared type to
ErrorType, which caused problems elsewhere.

Instead, generalize the logic used for AbstractFunctionDecl.
This correctly wires up the GenericTypeParamDecl's archetypes even
if the signature didn't validate, fixing crashes if the generic
parameters of the type are referenced.
