- Enable s_or_b64/s_and_b64/s_xor_b64 for v2i32. Add various additional
combines to make use of these newly legalised instructions.
- Update several tests and separate legacy r600 tests where necessary.
Add to the VOP patterns to recognise when or/xor/and are masking only the most significant bit of i32/v2i32/i64 and replace with the corresponding FP source modifier.
