[swift-dev] [Swift 2.2] IRGen: Work around crash lowering generic base class-constrained type parameter.

[Joe Groff]

Hey Joe, I have another fix being tested for a regression handling generic parameters constrained by dependent generic base class constraints:

https://github.com/apple/swift/pull/1257 (master)
https://github.com/apple/swift/pull/1258 (2.2)

I'd like to pull this into 2.2, with your approval.
