[PATCH] D17360: [cfi] Fix handling of sanitize trap/recover flags in the cross-DSO CFI mode.

[Evgeniy Stepanov via cfe-commits]

eugenis added a comment.

This lets us support the following case:
module A checks vcalls and casts, with diagnostics
module B checks vcalls but not casts (but it still has bitsets for vtables), with diagnostics
then a cast check from module A with a target in module B should print diagnostics instead of trapping

It's definitely not critical functionality, but could be nice to have, especially as it does not cost us anything.

And yes, CodeGenModule::NeedAllVtablesBitSet needs to be fixed for this work.

WDYT?
