Check for constant builtin value first.
The original code imported from EVRP for evaluating built_in_constant_p
didn't check to see if the value was a constant before checking the
inlining flag. Now we check for a constant first.
* gimple-range-fold.cc (fold_using_range::range_of_builtin_call): Test
for constant before any other processing.
