[LTO] Introduce a helper function collectImportStatistics (NFC) (#106179)
This patch introduces a helper function collectImportStatistics. The
new function computes statistics of imports for
ComputeCrossModuleImport and dumpImportListForModule with no
functional change.
The background is as follows. I'm planning to reduce the memory
footprint of ThinLTO indexing by changing ImportMapTy, the data
structure used for an import list. The new list will be a hash set of
tuples (SourceModule, GUID, ImportType) represented in a space
efficient manner. That means that obtaining statistics like the
number of definitions per source module requires us to go through the
entire import list (for a given destination module).
Introducing a helper function now makes the callers more independent
of the underlying data structures used in ImportMapT.
