	Iterator support through a pointer to some abstract cache.

Detailed Description

Default symbol cache implementation; stores associations between names (StringAttr's) to mlir::Operation's.

Adding/getting definitions from the symbol cache is not thread safe. If this is required, synchronizing cache acccess should be ensured by the caller.
