[PATCH] D32501: InferAddressSpaces: Infer from just addrspacecasts

[Matt Arsenault via Phabricator via llvm-commits]

Eliminates some more cases where some subset of the addressing
computation remains flat. Some cases with addrspacecasts    
in nested constant expressions are still left behind however.
