  [InstCombine] Use copyMetadata in PointerReplacer::replace (#201827)

PointerReplacer::replace creates a new load that differs from the
original only in its pointer operand; the loaded type is unchanged.  It
was using copyMetadataForLoad(), which is meant for the case where the
load's *type* changes.  Since the type is the same here, plain
copyMetadata() is correct and preserves all metadata directly.
