No progress yet with that, so for now, committed to gomp-4_0-branch in
r221411:

libgomp Fortran testing: for -g torture testing, disable variable tracking.
Otherwise, the nvptx-none offloading compiler will run into issues such as:
source-gcc/libgomp/testsuite/libgomp.fortran/examples-4/e.50.1.f90: In
function '__e_50_1_mod_MOD_vec_mult._omp_fn.1':
