[backport] Refactor the ClosureOptimizer, run ProdCons only once per …
…method Refactor and clean up the ClosureOptimzier. The goal of this change is to run the ProdCons analyzer only once per method, instead of once per closure instantiation. Bootstrapping scala with `-Yopt-inline-heuristics:everything` revealed that ProdCons can take a very long time on large methods, for example ``` [quick.compiler] scala/tools/nsc/backend/jvm/BCodeBodyBuilder$PlainBodyBuilder#genArithmeticOp - analysis: 1 spans, 17755ms [quick.compiler] scala/tools/nsc/typechecker/SuperAccessors$SuperAccTransformer#transform - analysis: 1 spans, 28024ms [quick.compiler] scala/tools/nsc/backend/jvm/BCodeBodyBuilder$PlainBodyBuilder#genInvokeDynamicLambda - analysis: 1 spans, 22100ms ``` With this change and enough time and space (-Xmx6000m), bootstrapping scala succeeds in this test mode.
