TGSI shader dump

While trying different settings in tesseract r600g gives me this for the
maximum setting of MLAA:

EE r600_shader.c:6180 tgsi_endif - if/endif unbalanced in shader
EE r600_shader.c:157 r600_pipe_shader_create - translation from TGSI failed !
EE r600_state_common.c:750 r600_shader_select - Failed to build shader variant
(type=1) -1

The offending TGSI shader is attachend. From a simple count of UIF end ENDIF it
seems that they are not unbalanced and the problem is somewhere else.
