  Log Message:
  -----------
  [OPENMP50]Do not mark the function as used if referenced only in declare
variant directive.

If the function is used only in declare variant directive as a variant
function, it should not be marked as used to prevent emission of the
target-specific functions. Build the reference in the unevaluated
context.
