cxx_stdcxxfs: Instantiate more code in the linking test
...
clang requires more instantiations than we currently have to exercise
their filesystem library.

cxx: remove test for the filesystem library
...
We no longer use compilers that rely on this library, and the 'null'
case in library detection was broken.

cxx: don't set stdc++fs globally
...
Linking to stdc++fs in the wrong order can produce an ICE under GCC.
Linking globally will place stdc++fs at the front of the library list
(which is the trigger for the ICE). We rely on the clients linking
manually where required.

We can't enable SSE3 if we want to compile for our Atom test target, so
we explicitly disable this and a few future instruction sets that we
