Abdiel Janulgue (6):
      i965/fs: Refactor check for potential copy propagated instructions.
      i965/fs: skip copy-propate for logical instructions with negated src entries
      i965/fs: copy propagate 'NOT' instruction when used with logical operation
      i965/vec4: skip copy-propate for logical instructions with negated src entries
      i965/vec4: copy propagate 'NOT' instruction when used with logical operation
      i965/disasm: Properly debug negate source modifier for logical instructions
