-IR: Implement Value::mergeUseLists() iteratively
-
-This avoids stack overflows when the the compiler does not perform tail call
-elimination. Apparently this happens for MSVC with the /Ob2 switch which
-may be used by external code including this header.
-
-Reported by and based on a patch from Jean-Francois Riendeau.
-
-Related to rdar://21900756
