sim: bfin: add OTP output port

This doesn't currently generate any interrupts (as there doesn't appear
to be any documentation to *when* it would even do so), but since the
HRM does say an interrupt line exists between the OTP and the SIC, add
one for completeness sake.  This will make a follow up patch easier.

extend scope of testing in gdb.ada/arrayptr

We add testing of taking a slice of an array access.  And we also
introduce the same amount of testing, but with an access to a
constrained array.

        * gdb.ada/arrayptr/foo.adb: Add access to constrained array.
        * gdb.ada/arrayptr.exp: Add new tests.

[Ada] fix printing slice of array defined as typedef

A change we are making in the compiler to help preserve useful
types when using -feliminate-unused-debug-types exposed a small
hole in our value-printing code.

One example of the problem happens when trying to print a slice
of an array pointer.  If the variable is defined as a pointer to
the typedef of an array, then we fail to print the slice, like so:

    (gdb) p arr_ptr(1..2)
    cannot take slice of non-array

gdb/ChangeLog:

        * ada-lang.c (ada_is_simple_array_type, ada_value_slice_from_ptr)
        (ada_value_slice, empty_array, to_fixed_array_type): Deal with
        typedefs.

improve Ada exception catchpoint MI notification

This rewrites the code generating the Ada exception catchpoint hit
notification for both the GDB/MI case as well as the non-MI case,
by using the relevant ui_out_* functions to generate the output.
the MI notifications for Ada exception catchpoints now include
the stop reason, and the breakpoint "disp", much like other breakpoint
events do.  It also introduces a new field "exception-name" for
exception catchpoints (excluding "failed assertion catchpoints,
where we just want to know that it was a failed assertion).

gdb/ChangeLog:

        * breakpoint.h (bpdisp_text): Add declaration.
        * breakpoint.c (bpdisp_text): Make non-static.
        * ada-lang.c: #include "mi/mi-common.h".
        (print_it_exception): Rewrite to improve GDB/MI output.

gdb/doc/ChangeLog:

        * gdb.texinfo (GDB/MI Ada Exception Information): Document
        the "exception-name" field in the *stopped async record.

gdb/testsuite/ChangeLog:

        * gdb.ada/mi_catch_ex: New testcase.

gdb/testsuite/
* gdb.cp/cpexprs.exp (Overloaded methods): No longer try the
base::overload(void) method without specifying "const".
