[PATCH] AsmParser: Extend the API to make the mappings from the numbers in the source to unnamed global values accessible to the library users.

[Alex Lorenz]

Hi dexonsmith, bob.wilson, bogner,

This patch creates a new SlotMapping struct in the AsmParser library which can be passed into the publicly accessible parsing functions in order to extract the data structures that map from numbers to global values and metadata nodes.

This patch would be useful for MIR serialization, as it would allow the MIR parser to lookup global values by their number and metadata nodes by their number.
