While porting the fortran acc routine changes from gomp4 to trunk, I
noticed that device was listed in the acc routine clause mask. That is
incorrect; it should be device_type not device. I fixed that problem in
the trunk patch submission. Here's the corresponding fix and test case
that I applied to gomp4.

As time permits, I'll add more test cases with invalid clause
combination for all of the constructs.
