This reduces allocations and also resolves some lurking inliner/inlinee line-number match problems. However, it does add about 1.5% to compile time. This fixes compiler OOMs seen compiling some large protobuf- derived inputs. For compiling the compiler itself, compilebench -pkg cmd/compile/internal/ssa -memprofile withcl.prof the numberlines-related memory consumption is reduced from 129MB to 29MB (about a 5% overall reduction in allocation). Additionally modified after going over changes with Austin to remove unused code (nobody called size()) and correct the cache-clearing code. I've attempted to speed this up by not using maps, and have not succeeded. I'd rather get correct code in now, speed it up later if I can. Updates #27739. Fixes #29279.
