Implement strict integer operations that panic on overflow This PR implements the first part of the ACP for adding panic on overflow style arithmetic operations (https://github.com/rust-lang/libs-team/issues/270), mentioned in #116064. It adds the following operations on both signed and unsigned integers: - `strict_add` - `strict_sub` - `strict_mul` - `strict_div` - `strict_div_euclid` - `strict_rem` - `strict_rem_euclid` - `strict_neg` - `strict_shl` - `strict_shr` - `strict_pow` Additionally, signed integers have: - `strict_add_unsigned` - `strict_sub_unsigned` - `strict_abs` And unsigned integers have: - `strict_add_signed` The `div` and `rem` operations are the same as normal division and remainder but are added for completeness similar to the corresponding `wrapping_*` operations. I'm not sure if I missed any operations, I basically found them from the `wrapping_*` and `checked_*` operations on both integer types.
