Auto merge of rust-lang#99908 - Nilstrieb:mir-opt-span, r=oli-obk
Show absolute line numbers if span is outside relative span In the MIR pretty printing, it can sometimes happen that the span of the statement is outside the span of the body (for example through inlining). In this case, don't display a relative span but an absolute span. This will make the mir-opt-tests a little more prone to diffs again, but the impact should be small. Fixes rust-lang#99854 r? `@oli-obk`
