ir_binop_bfm, ir_triop_bfi, ir_triop_bitfield_extract, and
ir_quadop_bitfield_insert too?
Adding ir_binop_bfm makes sense.
The next patch adds triop support.
I didn't add an ir_expression constructor with type inference for
quadops since I wasn't sure how to handle ir_quadop_vector (and it's the
only other quadop). But I guess it can be handled as:
glsl_type::get_instance(operands[0]->type->base_type,
operands[0] != NULL +
operands[1] != NULL +
operands[2] != NULL +
operands[3] != NULL,
1);
Then ir_builder::bitfield_extract() could use it.
