This reverts commit 2ab9990c9eb79682a4d4b183dfbc7612d3e55328. It has caused multiple build failures: * https://lab.llvm.org/buildbot/#/builders/177/builds/4346 * https://lab.llvm.org/buildbot/#/builders/180/builds/3803 * https://lab.llvm.org/buildbot/#/builders/175/builds/10419 * https://lab.llvm.org/buildbot/#/builders/191/builds/4318 * https://lab.llvm.org/buildbot/#/builders/173/builds/4274 * https://lab.llvm.org/buildbot/#/builders/181/builds/4297 All these bots failed with a time-out: ``` command timed out: 1200 seconds without output running [b'ninja', b'-j', b'32'], attempting to kill ``` I'm guessing that that's due to template instantiations failing at some point (https://reviews.llvm.org/D122441 introduced a custom implementation of std::visit). Everything seems fine when either: * building on X86 with GCC or Clang (tested with GCC 9.3 and Clang 12) * building on AArch64 with GCC (tested with GCC 11)
