splitBBWithSuffix() moves the instruction that CodeGenIP points to to a different block, but EmitCaptureStmt() is supposed to operate on the original block. It previously worked because the block and the iterator in CodeGenIP could go out of sync.

I've changed EmitCaptureStmt to only accept a BasicBlock instead of iterator, because that's the only thing it actually used. The use of `end()` here was basically arbitrary.
