Add 'libgomp.oacc-fortran/declare-allocatable-1-runtime.f90'
... which is 'libgomp.oacc-fortran/declare-allocatable-1.f90' adjusted for missing support for OpenACC "Changes from Version 2.0 to 2.5": "The 'declare create' directive with a Fortran 'allocatable' has new behavior". Thus, after 'allocate'/before 'deallocate', call 'acc_create'/'acc_delete' manually. libgomp/ * testsuite/libgomp.oacc-fortran/declare-allocatable-1-runtime.f90: New.

! passed to 'incr' may be unset, and in that case, it will be set to [...]",

! initialize counter variables:

! { dg-line l_dummy[variable c 0] }
|

! { dg-message dummy {} { target iN-VAl-Id } l_dummy } to avoid
