rG03b8c69d06f8: [PredicateInfo] Use Intrinsic::getDeclaration now that it handles unnamed types.
Summary

This is a second attempt to fix the EXPENSIVE_CHECKS issue that was mentioned In D91661#2875179 by @jroelofs.

(The first attempt was in D105983)

D91661 more or less completely reverted D49126 and by doing so also removed the cleanup logic of the created declarations and calls.
This patch is a replacement for D91661 (which must itself be reverted first). It only replaces the custom declaration creation with the generic version and shows the test impact.

Won't this also remove the declaration if there's a pre-existing use?

No, but it might remove a declaration that is available but not used.

jeroen.dobbelaere updated this revision to Diff 359682.Jul 19 2021, 12:38 AM

Only track newly introduced declarations for removal. Do not use the 'use count' to decide this.
