This is a followup to
084ea8ad584 OpenMP: middle-end support for dispatch + adjust_args.
This patch fixes a bug that caused arguments in an OpenMP dispatch call to be
modified even when no variant substitution occurred.
gcc/ChangeLog:
* gimplify.cc (gimplify_call_expr): Create variable
variant_substituted_p to control whether adjust_args applies.
