Detailed Description
IRMaterializationUnit is a convenient base class for MaterializationUnits wrapping LLVM IR.
Represents materialization responsibility for all symbols in the given module. If symbols are overridden by other definitions, then their linkage is changed to available-externally.

| ) |
Create an IRMaterializationLayer from a module, and pre-existing SymbolFlags and SymbolToDefinition maps.
The maps must provide entries for each definition in M. This constructor is useful for delegating work from one IRMaterializationUnit to another.
