FWIW, I also ran into cases triggered by this commit, where compilation of one file has started taking an excessive amount of time (unsure if it completes or not). It can be reproduced with this file: https://martin.st/temp/RegisterBankEmitter-preproc.cpp

With this file, compiled with `clang++ -target i686-w64-mingw32 -w -c -std=c++17 -O3 -fno-exceptions -fno-rtti RegisterBankEmitter-preproc.cpp`, used to take ~6 seconds before this commit. After this commit, it doesn't complete within at least 3 minutes.
