If an instruction is first legal instruction in the module, and is the only legal instruction in its basic block, it will be ignored by the outliner due to a length check inherited from the older version of the outliner that was restricted to outlining within a single basic block. This removes that check, and updates any tests that broke because of it. Reviewer: paquette Differential Revision: https://reviews.llvm.org/D120786
