Four simple patches which correct situations where we shift left into the sign bit of a signed integer type, which is undefined behaviour in C. These are by no means the only examples (even restricted to ARM board code; try "grep '1 << 31'"), but I'm vaguely aiming for "get 'make check' to not emit any clang -fsanitize=undefined warnings".
