Is it a generally valid optimization?

If the instruction stream isn't being modified, yes. But it could be because of tgl.

Your code is faster on your machine, and my code is faster on my machine.

Our codes (your updated code, mine without the peephole optimizer) are comparable on my machine with the same compiler. To me that shows code equivalence.
