Clean up asm code a bit. - Use vector instead of Array, reducing allocations. - Use vectors instead of deques since we only push_back and index. - Remove redundant typedefs of iterators. - Comment out unused variable (used only in commented-out GDC code). - A few whitespace changes.

void main()
{
  void foo() {}

  auto dg = &foo;

  if(dg.funcptr is null)
  { assert(0); }
}
