Fix for GitHub issue #199 : handle signed division overflow.
...
When performing a signed division or modulus operation using native
arithmetic, trap the special case that the numerator is the minimum
integer value and the denominator is -1, as this gives an undefined
result in C++.

...
Use test_joinable() and do_join() to ensure everything gets cleaned
up before the thread is reaped. This should fix br1016, br1017, and
br1018.

Handle mixed continuous and non-blocking assignments to same vector.
...
SystemVerilog allows a mixture of procedural and continuous assignments
to be applied to different parts of the same vector. The previous attempt
to make this work for non-blocking assignments was flawed (see preceding
fix for vvp_fun_part_pv::recv_vec4_pv). Instead, handle this case by
converting the non-blocking assignment into a delayed force statement,
which matches the way mixed continuous and blocking assignments are
handled.

Make .scope aware of return type, and extend %ret/vec4 operands

The .scope needs to be aware of return types so that the %call/vec4
function knows how to intialize the return value. We also need to
extend the %ret/vec4 to support writing parts of the return value.
