Generally it is optimized out.
The fine details resemble the analysis of correctness - all the evidence shows people expect per-iteration semantics with considerable frequency, and don’t rely on per-loop semantics with measurable frequency. But it’s impossible to completely automate that assessment. Likewise, it’s impossible to automatically detect code that will spuriously allocate because of the semantic transition.
