Olivier Fourdan e0bb4a1ec7 glamor: check max native ALU instructions 
When using glamor (either in Xephyr or Xwayland) on hardware with too
low instructions limit, glamor fallbacks to sw due to large shaders.

This makes glamor unbearably slow on such hardware.

Check reported value for GL_MAX_PROGRAM_NATIVE_ALU_INSTRUCTIONS_ARB
and fail in glamor_init() if the limit is lower than 128.
