[gomp] initial c++ support

[Richard Henderson]

There are many things missing yet for full support:

  * I still don't parse "for (int i = 0; ...)".  I'll have to poke about
    to see what I can do reusing existing parser bits, but still retain
    enough control to reliably extract "i" and "0" after the fact.

  * Don't handle types with constructors in data clauses.

  * Don't handle templates.

But this is good enough to run many of the C tests.
