New compile-time: https://llvm-compile-time-tracker.com/compare.php?from=33e41eaecdd7f71184b0bc9dbfdc2892aa45534a&to=bdf43c851f0f5f99df40af83f2d696df8babe7a8&stat=instructions
It's worth mentioning that contrary to your first patch (which had near zero impact on CTMark codegen), I'm seeing some significant code size changes with the new version: https://llvm-compile-time-tracker.com/compare.php?from=33e41eaecdd7f71184b0bc9dbfdc2892aa45534a&to=bdf43c851f0f5f99df40af83f2d696df8babe7a8&stat=size-text This might indicate a bug in the new implementation.
