Florian Hahn 6a6cc5542b [SimpleLoopUnswitch] Enable freezing of conditions by default. ...

This fixes a series of mis-compiles by SimpleLoopUnswitch.

My measurements showed no performance regression with -O3 on AArch64
in SPEC2006, SPEC2017 and a set of internal benchmarks.

Fixes #50387, #50430

Depends on D124251.
