SILGen: Emit curry thunks for generic functions.

SILGen learned how to forward archetypes for generic class constructors, and we can reuse this knowledge to finally implement curry thunks for generic functions.

Generic methods still pose a problem because we can't return a value of polymorphic type, so we'd need to hoist polymorphic parameters to the outermost uncurry level during SIL function type canonicalization even at uncurry level zero.
