Sometimes a transformation can change the name of some IR (e.g. an SCC with functions added/removed). This can be confusing when debug logging doesn't match the post-transformation name. The specific example I came across was that --print-after-all said the inliner was working on an SCC that only contained one function, but calls in multiple functions were getting inlined. After all inlining, the current SCC only contained one function. Piggyback off of the existing logic to handle invalidated IR + --print-module-scope. Simply always store the IR description and use that. Reviewed By: jamieschmeiser Differential Revision: https://reviews.llvm.org/D106290
