sim/igen: Fix linker error with -fno-common

GCC 10 enables -fno-common by default. This resulted in multiple

Remove stale -DNO_PROTOTYPES bits from gdb testsuite

The gdb.base/call-sc.exp, gdb.base/structs.exp and
gdb.base/structs2.exp testcases still try compiling the sources with
-DNO_PROTOTYPES, but the corresponding sources don't have any #ifdef
NO_PROTOTYPES any longer. Those were removed throughout years ago.

OTOH, gdb.base/ovlymgr.h does check for NO_PROTOTYPES, but no .exp
file compiles it with -DNO_PROTOTYPES.

gdb.base/reread.exp and gdb.base/varargs.exp set a 'prototypes'
global, which is a stale bit left behind when the "try-compiling
without and then with -DNO_PROTOTYPES" logic was around.

gdb/testsuite/ChangeLog:

* gdb.base/call-sc.exp (start_scalars_test): Use
prepare_for_testing and don't try compiling with -DNO_PROTOTYPES.
* gdb.base/overlays.c: Remove references to PARAMS.
* gdb.base/ovlymgr.h (PARAMS): Delete, and remove all references.
* gdb.base/reread.exp: Don't set 'prototypes' global.
* gdb.base/structs.exp (start_structs_test): Use
prepare_for_testing and don't try compiling with -DNO_PROTOTYPES.
* gdb.base/structs2.exp: Don't set 'prototypes' global. Use
prepare_for_testing and don't try compiling with -DNO_PROTOTYPES.
Don't issue "set width 0". Remove gdb_stop_suppressing_tests
call.
* gdb.base/varargs.exp: Don't set 'prototypes' global.

Remove stale overlay testcase bits

D10V support was removed years ago, but the gdb.base/d10vovly.c file
stayed behind. Looking a bit closer, I can't find anywhere that
references gdb.base/m32rovly.c either.

Both gdb.base/m32rovly.c and gdb.base/d10vovly.c seem to be older
copies of gdb.base/ovlymgr.c, that are exactly the same, except for
some cosmetic differences, and for missing _ovly_debug_event. Note
that gdb.base/ovlymgr.c has the #ifdef __M32R__ bits too. Note also
that gdb.base/overlays.exp is currently only supported on m32r, and
that uses ovlymgr.c not gdb.base/m32rovly.c.

gdb/testsuite/ChangeLog:

* gdb.base/d10vovly.c: Delete.
* gdb.base/m32rovly.c: Delete.
* gdb.base/ovlymgr.c: Remove all code guarded by __D10V__.

aarch64: Fix segfault on unicode symbols

This patch fixes a segfault which occurs when the AArch64 backend parses

gdb: remove unused fetch_inferior_event and inferior_event_handler parameters

I noticed that fetch_inferior_event receives the client_data parameter
from its caller, inferior_event_handler, but doesn't actually need it.
This patch removes it. In turn, inferior_event_handler doesn't use its
parameter, so remove it too.

The `data` argument used when registering
remote_async_inferior_event_handler is changed to NULL, to avoid
confusion. It could make people think that the value passed is used
somewhere, when in fact it's not.

Don't derive tui_data_item_window from tui_gen_win_info

There's no deep reason that tui_data_item_window should derive from
tui_gen_win_info -- it currently uses a curses window to render, but
that isn't truly needed, and it adds some hacks to other parts of the
TUI.

This patch changes tui_data_item_window so that it doesn't have a base
class, and updates the register window. This simplifies the code and
enables a subsequent cleanup.

Rename tui_data_item_window::item_no

tui_data_item_window::item_no is misnamed -- it only can be used for a
register, but it references a "display" number as well. (Based on

there were plans at one point to display variables in this window as
well. However, this was never implemented.)
