Summary: This caused incorrect debug information for parameters: Previously, after a COPY of a parameter that changes the width, we would emit a DBG_VALUE that continues to be associated to that parameter, even though it now used a different width. This made the LiveDebugValues pass assume the parameter value got clobbered and it stopped tracking the parameter entry value, leading to incorrect debug information.
