ValueMapper: fix assertion when null-mapping a constant for linking metadata Summary: When RF_NullMapMissingGlobalValues is set, mapValue can return null for GlobalValue. When mapping the operands of a constant that is referenced from metadata, we need to handle this case and actually return null instead of mapping this constant.
