Cross thinLTO might result in performance loss? #156

I haven't tested myself and I kinda introduced another variable into it, but I built my Firefox fork with it, and got an issue about performance being worse. I went back to old LTO and performance is right back where it was according to the guy.

Does this affect Speedometer 3.0 (Javascript) and Stylebench (CSS) benchmarks? So far i got the same performance as in Chrome in Speedometer 3.0 with SSE4 and AVX2 variants.
