[Swift-devel] Format of site tests

The site tests as I left them were pretty much: 
  for each site file in $SOMEDIR:
     run some subset of the local tests with that site file

I think I made the subset of the local tests be one that would test 
"site-like functionality" eg file transfer and job submission, rather than 
"language-like functionality" eg the boolean not-operator.

That structure didn't allow some things that would have been good to 
regularly test - eg. running a 1000 NOP job test through coasters on a 
site, while not running that test on a pure GRAM2 site, where such a run 
would be hilarious/tragic.
