  Log Message:
  -----------
  Give C compiler -fno-reorder-blocks -funwind-tables if they are accepted.
gcc accepts both.
clang accepts one of them.

The point of unwind-tables is to prepare for a future in which we generate
code using C++ exception handling. This helps us exercise *some* of that earlier.

  -----------
  Workaround for https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67183.
Establish a partial ordering of the outputs, so that stubs precede non-lazy pointers.
Note that I couldn't get weak references to occur (even in C).
Note that I still think we shouldn't output in hash order, but I didn't fix that.
