Bill Wendling d3c9d971e6 If we are extracting a basic block that ends in an invoke call, we must also ...

extract the landing pad block. Otherwise, there will be a situation where the
invoke's unwind edge lands on a non-landing pad.

We also forbid the user from extracting the landing pad block by itself. Again,
this is not a valid transformation.
