      Overhaul emit_compare() function. · e6aeb24b
      Brian Paul authored
      Previously, comparing vec2, vec3, vec4 was broken.
      Added IR_EQUAL, IR_NOTEQUAL nodes/operators to compute boolean
      equality/inequality vs. IR_SEQUAL/IR_SNEQUAL which work component-wise.
      Use IR_EQUAL/IR_NOTEQUAL for the == and != operators.
      To compute vec4 equality, use SNE, DP4, SEQ instruction sequence.
