Mehdi Amini bcc47419d9 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.
