Is it not true in Ada that if something is a particular type, then
it has the properties (including alignment) of that type?
The other issue is that DECL_USER_ALIGN is supposed to indicate if an
alignment was specified *for a decl*. If you want to know if an
alignment is specified for *the type of a decl*, you check
TYPE_USER_ALIGN (TREE_TYPE (decl)). Some code may wish to do
something if *either* alignment was user-specified, but then it can
check *both* flags.
