[PATCH] D123473: [LICM] Only create load in pre-header when promoting load.

@regehr If you have time, it would be nice to fuzz LICM to check if this assertion can be triggered (after the patch lands).
It needs a function with the `writeonly` attribute + a pointer as input (or a global variable), a loop with a store to said pointer, a phi, and that's it (i.e., the test cases here as seed). Then some random stuff to make it crash.
Thanks!
