[openacc] acc loop updates in fortran

This patch updates the fortran front end so that it supports the acc
loop clauses in a similar manner to both the c and c++ front ends in
addition to addressing a couple of other loose ends. Specifically:

 * the tile clause now supports a list of arguments like c and c++

 * made the default clause parser aware that openacc only supports

 * error when no data clauses are used in an update construct

 * corrects the way that reduction errors are detected for duplicate

 * add support for the gang static argument and the auto clause

Besides for that, a number of tests have either been updated or added.

Is this OK for trunk?
