This increases the test coverage for XFA: - Multiple entries are added from a single file - Priorities are assigned to enforce a given order - The size of the `struct` to add is changed to no longer be a power of 2 (cherry picked from commit 2839224)
This changes the API of xfa from
XFA(array_name, prio) type element_name = INITIALIZER;
to
XFA(type, array_name, prio) element_name = INITIALIZER;
this allows forcing natural alignment of the type, fixing failing tests
on `native64`.
(cherry picked from commit 2b6f65a)

It's just an internal API and if things work correctly, users shouldn't even notice the change - only when they hit the alignment bug, and this one fixes that. |
