[LPM] Use a map from analysis ID to immutable passes in the legacy pass manager to avoid a slow linear scan of every immutable pass and on every attempt to find an analysis pass. This speeds up 'check-llvm' on an unoptimized build for me by 15%, YMMV. It should also help (a tiny bit) other folks that are really bottlenecked on repeated runs of tiny pass pipelines across small IR files. llvm-svn: 247240 GitOrigin-RevId: b1e3a9ae8d30e23186f08548f9bd3ba79c09ea1c
