    [osr] Fall back to synchronous OSR on cache mismatches · 3f5a3df6
    Jakob Gruber authored
    If we've already cached OSR'd code for the current function but with a
    different osr offset, fall back to synchronous compilation. This avoids
    degenerate cases where we repeatedly spawn OSR jobs but then fail to
    install them.
    
    Drive-by: More consistent --trace-osr output.
    Drive-by: Rename kCompileForOnStackReplacement to kCompileOptimizeOSR
    for name consistency.
    Drive-by: Add JSFunction::DebugNameCStr() for more convenient PrintF's.
