There are a number of glitches when pretty-printing type names.
This is particularly true for derived types like pointer to functions,
array of pointer to functions and the likes.
For instance, we can see in
tests/data/test-abidiff-exit/PR30048-test-2-report-1.txt that a
function N that takes no parameter and returns a pointer to an array
of 7 int is pretty-printed as:
int[7]* N()
That obviously doesn't respect the type naming rules of C or C++.
With this patch, function N is declared as:
int(*N(void))[7]
To learn more about the impact of the patch on how types are
pretty-printed, you can look at the parts of the patch that are
adjustments to the expected output of the regression tests.
For instance, here is how the expected output of type pretty-printing
in tests/data/test-abidiff-exit/PR30048-test-2 is modified by this
patch:

Note that the change to the CTF test
tests/data/test-read-ctf/test9.o.abi is triggered by a change in the
sorting of types because types are sorted alphabetically.
All in all, this is clearly an overdue improvement to the type name
pretty-printing.
