Fix crash with GNAT minimal encodings
Running the AdaCore internal test suite with -fgnat-encodings=minimal
found a gdb crash. The bug is that GDB ends up with a typedef in
ada_index_type, resulting in a NULL dereference.
This crash can be reproduced using GCC 11 with the included test case.
Tested on x86-64 Fedora 32. Because this is Ada-specific, and was
already reviewed by Joel, I am going to check it in.

* ada-lang.c (ada_index_type): Use ada_check_typedef.
