Adjust 'libgomp.c/declare-variant-{3,4}-[...]' for inter-procedural value range propagation

..., that is, commit 53ba8d669550d3a1f809048428b97ca607f95cf5
"inter-procedural value range propagation", after which we see:

    [-PASS:-]{+FAIL:+} libgomp.c/declare-variant-3-sm30.c scan-nvptx-none-offload-tree-dump optimized "= f30 \\(\\);"

Etc.  That's due to:

It's nice to see this optimization work here, too, but it does interfere with
how we're currently testing OpenMP 'declare variant'.
