Ravi Kandhadai e3a8a96469 [OSLogOptimization] Fix the symbolic closure folding code to only create ...

new closures when all captures of the symbolic closure, including address-typed
captures, are symbolic constants. For other closures, they must have been
autoclosures passed to the log call and therefore they need not be duplicated
but reused as such.

This eliminates the need to copy_value the non-constant captured values of
closures. Instead the closure itself is copied as a whole.
