nir: add ir3-specific bitwise triop opcodes

Browse source 
ir3 has a number of bitwise triops (e.g., shrm == (src0 >> src1) & src2)
that don't have NIR-equivalents. Doing instruction selection for them is
a lot more convenient using algebraic patterns than to have to manually
match for them. This patch add NIR opcodes for these instructions.
