NOP_FUNCTION is a drop-in function replacement that ignores its
arguments but also suppresses compiler warnings about them being unused.
For example, on MSVC, 0(foo, bar, baz()); or __noop(foo, bar, baz());
would suppress warnings about foo and bar being unused and not call baz
at all. Neither of those syntaxes is supported on GCC, which provides no
similar way to suppress unused variable warnings, but we can at least
allow such code to compile by defining NOP_FUNCTION to be an empty
variadic macro.
