Merged revision(s) 81608-81610 from trunk:

Browse Source 
Optimization: Add specializations of make_array_helper, allocate_array_helper, and array_deleter for fixed size arrays to avoid storing size.
........
Consistent formatting across overloads of make_shared and allocate_shared (array forms).
........
More consistency in type parameters in helper details of allocate_shared and make_shared.
........
