tests: add more coverage for 128 bit operations

- fixup 128-bit atomics test to only run on x86_64
- add truncation test for 128-bit types, including non power of two targets (there was a bug with broken non-power-of-two truncation in the cbe)
- add 128-bit binary not test (covers another bug fixed in the cbe)
