Since this test is supposed to check the order in which globals are presented
after AST reordering, such oracle changes must be considered carefully. Here,
there's no dependency between `j` and `k`, so that they can indeed be swapped.
This in fact better reflect the original global list before reordering

NB: `l` is always at the very top of the list, despite being inserted last. This
might warrant investigation at some point. However, the resulting AST after
reordering is correct, which is the main goal.

Pretty-printing _Static_assert was already hackish for the "not-a-struct-field"
case, and for the latter, it was incorrect: conversion between Cabs expressions
and Cil expressions does not work in every case; the normalized version was
not always identical to the original one; etc.
For now, we consider _Static_assert's not to be essential in pretty-printing.
This "revert-like" commit ensures the code is available in the history, if
we need it later.

Some more refactoring might not be totally useless

most differences in Eva oracles come from the fact that now anonymous arguments are taken into
account when generating default assigns for prototypes with empty specs.
