[ORC] Apply MachO::CPU_SUBTYPE_MASK to comparison in getDylibInterfac… (#145154)
…eFromDylib.
When comparing CPU subtypes from slices in a MachO universal binary we
need to apply the MachO::CPU_SUBTYPE_MASK to mask out any flags in the
high bits, otherwise we might fail to correctly match a slice and return
a spurious "does not contain slice" error.
