Nikita Popov	03aceab08b	[ValueTracking] Enable -branch-on-poison-as-ub by default Now that SimpleLoopUnswitch and other transforms no longer introduce branch on poison, enable the -branch-on-poison-as-ub option by default. The practical impact of this is mostly better flag preservation in SCEV, and some freeze instructions no longer being necessary.

[ValueTracking] Enable -branch-on-poison-as-ub by default

Now that SimpleLoopUnswitch and other transforms no longer introduce
branch on poison, enable the -branch-on-poison-as-ub option by
default. The practical impact of this is mostly better flag
preservation in SCEV, and some freeze instructions no longer being
necessary.

[SCEV] Add test for non-unit stride with multiple exits (NFC)

We currently can't determine any exit counts here, because there
is no "controlling exit".
