i965/fs: Add support for bit instructions.
Don't bother scalarizing ir_binop_bfm, since its results are
identical for all channels.
v2: Subtract result of FBH from 31 (unless an error) to convert
MSB counts to LSB counts.
v3: Use op0->clone() in ir_triop_bfi to prevent (var_ref
channel_expressions) from appearing multiple times in the IR.
