Auto merge of #10827 - y21:large-stack-frames, r=dswij
new lint: `large_stack_frames` This implements a lint that looks for functions that use a lot of stack space. It uses the MIR because conveniently every temporary gets its own local and I think it maps best to stack space used in a function. It's probably going to be quite inaccurate in release builds, but at least for debug builds where opts are less aggressive on LLVM's side I think this is accurate "enough". (This does not work for generic functions yet. Not sure if I should try to get it working in this PR or if it could land without it for now and be added in a followup PR.) I also put it under the nursery category because this probably needs more work... changelog: new lint: [`large_stack_frames`]
