// PLEASE READ THIS!
//
// This test is specifically to test out individual instruction interactions,
// not for crashers. The idea is to make it so that we have one test for every
// SIL instruction, so please add a test here when you add a new instruction.
//
// For assign/lookthrough, just add a test that triggers an ownership error. If it is
// a more complex instruction, talk with @gottesmm.
