progress on example 93 to demonstrate trapping all potential exceptions at compile time
...
removed constexpr from exception policies.
this eliminates obstacle to gcc compilation which doesn't support constexpr throw
unfortunately, all versions of gcc trip compiler fault so gcc not supported for now
safe_literal - make this an unsafe type since it doesn't have policies - this might change in the future

testing constexpr for calculation of compile time overflows.
...
Turns out that clang doesn't just overflow - it traps if there's an overflow - basically like safe<int> does at compile time.
Upshot is we have to trap overflows at compile time WITHOUT calculating them. In retrospect this is undefined behavior but no matter.
Next iteration will deal with this.
