This commit creates a new structure called 'SlotMapping' in the AsmParser library. This structure can be passed into the public parsing APIs from the AsmParser library in order to extract the data structures that map from slot numbers to unnamed global values and metadata nodes. This change is useful for MIR Serialization, as the MIR Parser has to lookup the unnamed global values and metadata nodes by their slot numbers. Reviewers: Duncan P. N.
