    PPC: Debugger: prepare code for debugging on a per-function basis. · 9c269424

    Original commit message:
        Prior to this patch, we enter a global debug mode whenever a break point
        is set. By entering this mode, all code is deoptimized and activated
        frames are recompiled and redirected to newly compiled debug code.
    
        After this patch, we only deoptimize/redirect for functions we want to
        debug. Trigger for this is Debug::EnsureDebugInfo, and having DebugInfo
        object attached to the SFI prevents optimization/inlining.
    
        The result is that we can have optimized code for functions without break
        points alongside functions that do have break points, which are not
        optimized.
