Thanks! Besides disabling load folding, it would be great if `DoLocalEscapeAnalysis` could also prevent any additional work introduced by this changeset (data structure allocation etc.), so that we can use it to evaluate its impact on compilation speed. I'll continue looking at the patch when I'm back from vacation.
