PR fortran/65597
	* trans-openmp.c (gfc_trans_omp_do): For !simple simd with explicit
	linear clause for the iterator set OMP_CLAUSE_LINEAR_NO_COPYIN.
	For implcitly added !simple OMP_CLAUSE_LINEAR set it too.  Use step 1
	instead of the original step on the new iterator - count.

	* testsuite/libgomp.fortran/pr65597.f90: New test.
