RFC: adding `__builtin_verbose_trap(string-literal)`

[user1984]

@varconst

void foo(int* p) {
  if (p == nullptr)
    __builtin_verbose_trap("Argument must not be null");
}

Even better, use compile_assert P4021 proposed to C++ - it will stop the build, there will be no bug in production code. This is a zero runtime cost, it is 100% at compile time with Clang, GCC, MSVC supported.

void foo(int* p)

{
compile_assert(nullptr!=p, “Argument must not be null”);

// your code
}
