KT-15112, KT-15631
Revert changes for "tolerant to uninitialized values" in OptimizationBasicInterpreter: this approach doesn't converge for some specific cases where local variable is reused (e.g., in several inlined functions - see https://youtrack.jetbrains.com/issue/KT-15112). Instead, treat fake always-false conditional jump in the beginning of the post-condition loop as a "reference point" for stack on loop break / continue. This requires an extra abstraction layer in FixStackAnalyzer, since we can't perform fine-grain manipulations on Frames (such as "combine frame C from local variables of frame A and stack of frame B"). NB additional NOPs will be generated for post-condition loops. Should make a separate bytecode postprocessing pass to get rid of unnecessary NOPs (several YT issues for perceived quality of the generated bytecode are about such NOPs).
