Michael Tautschnig 3a28687fcd Define big-int operators for signed long 
Trying to use numeric_cast_v<signed long> resulted in ambiguous overload errors.
At the moment, we are in a few places wrongly using
`numeric_cast_v<std::size_t>` when it should be
`numeric_cast_v<std::ptrdiff_t>`. On non-Windows platforms, `std::ptrdiff_t` is
`signed long`. To enable the use of the correct `numeric_cast_v`, we need to
support the comparison operators.

About

CBMC is a Bounded Model Checker for C and C++ programs. It supports C89, C99, most of C11 and most compiler extensions provided by gcc and Visual Studio. It also supports SystemC using Scoot. It allows verifying array bounds (buffer overflows), pointer safety, exceptions and user-specified assertions. Furthermore, it can check C and C++ for consistency with other languages, such as Verilog. The verification is performed by unwinding the loops in the program and passing the resulting equation to a decision procedure.

For full information see cprover.org.
