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.

+
+! { dg-additional-options -Wopenacc-parallelism }
+
+! It's only with Tcl 8.5 (released in 2007) that "the variable 'varName'
+! passed to 'incr' may be unset, and in that case, it will be set to [...]",
+! so to maintain compatibility with earlier Tcl releases, we manually
+! initialize counter variables:
+! { dg-line l_dummy[variable c 0] }
+! { dg-message dummy {} { target iN-VAl-Id } l_dummy } to avoid
+! "WARNING: dg-line var l_dummy defined, but not used".
