Auto merge of #44249 - pnkfelix:debugflag-emit-end-regions, r=arielb1
Debugflag: -Z emit-end-regions Skip EndRegion emission by default. Use `-Z emit-end-regions` to reenable it. The main intent is to fix cases where `EndRegion` emission is believed to be causing excess peak memory pressure. It may also be a welcome change to people inspecting the MIR output who find the EndRegions to be a distraction. (In later follow-up PR's I will put in safe-guards against using the current mir-borrowck without enabling `EndRegion` emission. But I wanted this PR to be minimal, in part because we may wish to backport it to the beta channel if we find that it reduces peak memory usage significantly.)
