cmd/compile: fix reassignment check CL 65071 enabled inlining for local closures with no captures. To determine safety of inlining a call sites, we check whether the variable holding the closure has any assignments after its original definition. Unfortunately, that check did not catch OAS2MAPR and OAS2DOTTYPE, leading to incorrect inlining when a variable holding a closure was subsequently reassigned through a type conversion or a 2-valued map access. There was another more subtle issue wherein reassignment check would always return a false positive for closure calls inside other closures. This was caused by the Name.Curfn field of local variables pointing to the OCLOSURE node instead of the corresponding ODCLFUNC, which resulted in reassigned walking an empty Nbody and thus never seeing any reassignments. This CL fixes these oversights and adds many more tests for closure inlining which ensure not only that inlining triggers but also the correctness of the resulting code.
