So, shmput10 is now equally fast with Mesa-17.3.6 and Mesa-27.2.4 - however the
real-world workload still suffers.

Please have a look at http://93.83.133.214/downloads/JXRenderMark-1.0.1.zip -
it is a stand-alone benchmark which emulates the XRender sequences generated by
the Java XRender backend.

CentOS-7 + updates (Mesa 17.0.1):
./render 3 32 3 32 3 32 3 32 3 32 3 32 3 32
18621.335408 Ops/s; put composition (!); 32x32
18901.781304 Ops/s; put composition (!); 32x32
18903.572785 Ops/s; put composition (!); 32x32

Fedora 27 + updates (Mesa 17.3.6):
./render 3 32 3 32 3 32 3 32 3 32 3 32 3 32
[ce at localhost temp]$ ./JXRenderMark-1.0.1 3 32 3 32 3 32 3 32 3 32 3 32
6938.738245 Ops/s; put composition (!); 32x32
6825.050537 Ops/s; put composition (!); 32x32
6955.692404 Ops/s; put composition (!); 32x32

So there it is ... the slowdown of factor 2,5 :/
