[PATCH] Revert "r600g: set round_mode to truncate and get rid of  tgsi_f2i on
evergreen"

I see some regression with both compilers. Have you tested it with non-llvm
compiler? IIRC you are using BARTS card?

It seems the issue is triggered by the combination of commits:

60bf0f05 "r600g: set round_mode to truncate and get rid of tgsi_f2i on
evergreen"  and 
04e32400 "gallium: remove PIPE_SHADER_CAP_OUTPUT_READ".

Reverting any of them fixes the problem for me, I'll try to figure out what
exactly is going wrong. You might want to test the attached patch (reverts
first commit).
