[PATCH] D22115: Teach FastISel about thiscall (and, hence, about callee-pop).

[Nico Weber via llvm-commits]

thakis added a comment.

I looked through a few recent changes to X86FastISel.cpp. Most don't test the early-out branches at all. The ones that fix bugs with commit messages like "bail out to SelectionDAG since it gets this right" usually check that the right code is generated, like the new test I added now does here.

(ps: It's a bit weird that `retl $65536` silently assembles to `ret 0`)
