Why we created this variable. Mostly these will be RegionVariableOrigin::NLL, but some variables get created elsewhere in the code with other causes (e.g., instantiation late-bound-regions).

True if this is a universally quantified region. This means a lifetime parameter that appears in the function signature (or, in the case of a closure, in the closure environment, which of course is also in the function signature).

If this is 'static or an early-bound region, then this is Some(X) where X is the name of the region.
