cd2bbcba5b Fix bounded variable precision cpp_int's. 
1) Removed some constexpr optimizations which were causing the code to fail to spot that truncation/overflow had occurred.
2) Change min/max code for numeric_limits to work for bounded variable precision types (this needs more work as the current code relies on being able to create a fixed-precision allocator-free type of equivalent width.
3) Add tests for bounded variable precision integers.
