* proc: flag variables correctly when range-over-func stmts are used Argument variables of a range-over-func body closure should be returned flagged as normal local variables, not as function arguments. Updates #3806 * proc: for optimized functions allow .closureptr to not exist For optimized functions .closureptr is sometimes omitted from DWARF, allow it to be 0 and try to recover the range-over-func stack by best effort. Fixes #3806
