[Mesa-dev] [PATCH 0/3] v2 Allow the drivers to control output reads removal

[Vadim Girlin]

These patches are adding new pipe shader cap to allow omitting
output->temp transformation when shader is reading output values.

v2: use pipe_shader_cap enum instead of pipe_cap

  gallium: add PIPE_SHADER_CAP_OUTPUT_READ
  st/mesa: use PIPE_SHADER_CAP_OUTPUT_READ
  r600g: handle PIPE_SHADER_CAP_OUTPUT_READ
