1. wasm: Increase default stack size to 1MB …

   This commit increases the dfeault stack size allocated to the
   wasm32-unknown-unknown target to 1MB by default. Currently the default stack
   size is one wasm page, or 64 kilobytes. This default stack is quite small and
   has caused a stack overflow or two in the wild by accident.
   
   The current "best practice" for fixing this is to pass `-Clink-args='-z
   stack-size=$bigger'` but that's not great nor always easy to do. A default of
   1MB matches more closely with other platforms where it's "pretty big" by
   default.
   
   Note that it was tested and if the users uses `-C link-args` to pass a custom
   stack size that's still resepected as lld seems to take the first argument, and
   where rustc is passing it will always be last.
