Add noreturn declaration compatible with the MSVC compiler.

Browse Source 
MSVC provides a compiler declaration to declare that a function
never returns. This declaration is required in front of the
function definition rather than at the end, but fortunately gcc
is compatible with this location as well.

Explicit returns are no longer required after calls to test_die.
