bug#41615: [feature/native-comp] Dump prettier C code.

Amazing.I took a closer look at the code that uses casts to bools and
I think I found a
bug.

Casting to bool using an enum is equivalent to taking the lowest byte using
a byte mask. This wrongly casts to "false" integers whose lowest byte is nil.

bool cast_from_unsigned_long_long_to_bool (unsigned long long x)
{
  return (x & 0xFF);
}

The correct way to cast to bool is to mimic C semantics:

bool cast_from_unsigned_long_long_to_bool (unsigned long long x)
{
  if (x != 0)
    return true;
  else
    return false;
}

Am I right?

Nico.
