compiler/nir: add a lowering pass to convert the bit size of ALU operations
Not all bit-sizes may be supported natively in hardware for all operations. This pass allows drivers to lower such operations to a bit-size that is actually supported and then converts the result back to the original bit-size. Compiler backends control which operations and wich bit-sizes require the lowering through a callback function. v2: generalize this pass and make it available in NIR core (Rob, Jason) v3: remove some temporaries and reduce nesting in instruction loop using a continue statement (Jason) Reviewed-by: Jason Ekstrand <[email protected]>
