Implement on-stack replacement for arm/arm64/x86/x86_64. High-level overview: - osr_method_threshold is used to know when to compile a method in osr mode (-> treat all loops as irreducible). - branch instructions in the compiler query whether they can jump to an osr method. - An osr entry point is found through the stack maps: if a stack map is duplicated in the CodeInfo, it is an osr entry point.
