Apparently Clang does not have __builtin_foo_overflow_p()

Fixes #2044.

Sergey Bugaev 361a1b54d7 AK: Add Checked::addition_would_overflow() 
And switch the two-argument version of Checked::multiplication_would_overflow()
to use __builtin_mul_overflow_p(). This helps GCC optimize the code better.

Andreas Kling 63b8c6913c AK: Add Checked<T>::multiplication_would_overflow() 
This allows you to comfortably test if multiply 2 or 3 values would
cause arithmetic overflow.

Andreas Kling 9c54bad241 AK: Add a Checked<T> template 
A Checked<T> is a boxed integer type that asserts if you try to use its
value after an arithmetic overflow.
