safe_ops: Avoid signed overflow in Negate()

Negation of values such as -9223372036854775808 can't be represented in
signed equivalents (such as long long), leading to signed overflow.
Therefore, we can just invert bits and add 1 to perform this behavior
with unsigned arithmetic.

safe_ops: Implement safe shifting operations

Implement shifiting operations that perform consistently across architectures
without running into undefined or implemented-defined behaviour.
