So obviously this is a nice improvement even here. I could probably try around a bit and see if there is an even better fit with a different selections of header files, but even without that, I'd say this patch is by itself as good for clang as it is for gcc.

I could not improve matters much. There was very small differences between setting the limit at 110, 130 (BKM), 150 or 200:

real    3m6,322s user    19m3,000s sys    1m41,252s hotspot new pch BKM (on and above 130)

real    3m6,309s user    19m2,764s sys    1m41,488s hotspot new pch on and above 110

real    3m7,515s user    19m6,470s sys    1m42,345s hotspot new pch on and above 150

real    3m8,497s user    19m15,851s sys    1m42,494s hotspot new pch on and above 200
