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.
