* Implement -Wtruncation=level -Wtruncation=0 is the same as the current -Wno-truncation. -Wtruncation=2 is the same as the current -Wtruncation. -Wtruncation=1 is the new default; it's less strict, allowing N-bit values to be between -2**N and 2**N (exclusive). * Implement generic "parametrized warning" system * Test more `Wtruncation` variants Co-authored-by: ISSOtm <eldredhabert0@gmail.com>
