+Improved: The setup of MappingQGeneric::InternalData within the constructor of
+FEValues would previously unconditionally allocate memory for all shape
+functions and all quadrature points, also for the case where we use the tensor
+product and the full interpolation is unnecessary. This has been fixed,
+improving the situation for very high orders and numbers of quadrature points
+(e.g., avoiding 400 MB of memory for mapping degrees of 15 with $16^3$
+quadrature points in 3D).
