i965/fs: Use the LRP instruction for ir_triop_lrp when possible.
v2 [mattst88]:
- Add BRW_OPCODE_LRP to list of CSE-able expressions.
- Fix op_var[] array size.
- Rename arguments to emit_lrp to (x, y, a) to clear confusion.
- Add LRP function to brw_fs.cpp/.h.
- Corrected comment about LRP instruction arguments in emit_lrp.
v3 [mattst88]:
- Duplicate MAD code for LRP instead of using a function pointer.
- Check for != GRF instead of == IMM in emit_lrp.
- Lower LRP on gen < 6.
