If set, this RTDyldObjectLinkingLayer instance will claim responsibility for any symbols provided by a given object file that were not already in the MaterializationResponsibility instance.
Setting this flag allows higher-level program representations (e.g. LLVM IR) to be added based on only a subset of the symbols they provide, without having to write intervening layers to scan and add the additional symbols. This trades diagnostic quality for convenience however: If all symbols are enumerated up-front then clashes can be detected and reported early (and usually deterministically). If this option is set, clashes for the additional symbols may not be detected until late, and detection may depend on the flow of control through JIT'd code. Use with care.

Instructs this RTDyldLinkingLayer2 instance to override the symbol flags returned by RuntimeDyld for any given object file with the flags supplied by the MaterializationResponsibility instance.
This is a workaround to support symbol visibility in COFF, which does not use the libObject's SF_Exported flag. Use only when generating / adding COFF object files.
FIXME: We should be able to remove this if/when COFF properly tracks exported symbols.

Set the 'ProcessAllSections' flag.
If set to true, all sections in each object file will be allocated using the memory manager, rather than just the sections required for execution.
This is kludgy, and may be removed in the future.
