MIPS/GAS: Correct default ABI selection for `mips64*-ps2-elf*'

Correct an issue with the `mips64*-ps2-elf*' target introduced with
commit e407c74b5b60 ("Support for MIPS R5900 (Sony Playstation 2)"),

s390: Clean up s390-linux-tdep.c

After moving big parts of the code to the new s390-tdep.c file
s390-linux-tdep.c now contains many includes it doesn't need anymore.
Furthermore, there are some functions lacking a description.

Fix both and order the remaining includes alphabetically.

gdb/ChangeLog
* s390-linux-tdep.c: Remove unneeded includes and order them
alphabetically. Add comments to functions without description.

s390: Move record-replay to s390-tdep.c

Record-replay is independent of the OS. So it can be moved to the common
s390 code without problem.

s390: Split up s390-linux-tdep.c into two files

Currently all target dependent code for s390 is in one file,
s390-linux-tdep.c. This includes code general for the architecture as
well as code specific for uses in GNU/Linux (user space). Up until now
this was OK as GNU/Linux was the only supported OS. In preparation to
support the new Linux kernel 'OS' split up the existing s390 code into a
general s390-tdep and a GNU/Linux-specific s390-linux-tdep.

Note: The record-replay feature will be moved in a separate patch. This
is simply due to the fact that the combined patch would be too large for
the mailing list. This requires setting the process_record hook during
OSABI init to keep the code bisectable. The patch moving record-replay
cleans up this hack.

s390: gdbarch_tdep add hook for syscall record

Most parts of s390_process_record are common for the architecture. Only
the system call handling differs between the OSes. In order to be able to
move s390_process_record to a common code file add a hook to record
syscalls to gdbarch_tdep. So every OS can implement their own handling.

gdb/ChangeLog:

* s390-linux-tdep.c (gdbarch_tdep.s390_syscall_record): New hook.
(s390_process_record, s390_gdbarch_tdep_alloc)
(s390_linux_init_abi_any): Use/set new hook.

s390: Hook s390 into OSABI mechanism

Do what the title says and distinguish between 31- and 64-bit systems.
The goal is to init the OSABI as late as possible in gdbarch_init so the
OSABI has the chance to overwrite the defaults.

There are two pitfalls to be aware of:

First, the dwarf2 unwinder must be appended before the OSABI is
initialized. Otherwise the OS could add a default unwinder which always
takes control before the dwarf unwinder even gets a chance.

Second, tdesc_use_registers has to be handled with extra care. It sets
several gdbarch hooks, especially gdbarch_register_name, which has to be
overwritten again after the call. Furthermore it deletes the tdesc_data
without checking. Therefore there must not be a call to
tdesc_data_cleanup afterwards or GDB will crash with a double free.

gdb/ChangeLog:

* s390-linux-tdep.c (osabi.h): New include.
(s390_linux_init_abi_31, s390_linux_init_abi_64)
(s390_linux_init_abi_any): New functions.
(s390_gdbarch_init, _initialize_s390_tdep): Adjust.

s390: if -> gdb_assert for tdesc_has_registers check

Before doing the tdesc validation there is a check whether the tdesc has
registers or not. This check is not only unnecessary but wrong.

First the check is done after a default tdesc is assigned if the original
tdesc has no registers. These default tdescs always have registers so the
check alway returns true.

Second if the default tdesc would not have registers the check only skips
the tdesc validation instead of returning an error. This would trigger a
gdb_assert later on in tdesc_use_registers.

gdb/ChangeLog:

* s390-linux-tdep.c (s390_gdbarch_init): Use gdb_assert for
tdesc_has_registers check

s390: Move tdesc validation to separate function

Simplify s390_gdbarch_init by moving the target description validation to
a separate function.

gdb/ChangeLog:

* s390-linux-tdep.c (s390_tdesc_valid): New function.
(s390_validate_reg_range): New macro.
(s390_gdbarch_init): Adjust.

s390: gdbarch_tdep add field tdesc

Add a field for the target description to gdbarch_tdep. This will later be
needed to pass the 'correct' target description from osabi_init to
gdbarch_init. Unfortunately this cannot be done using gdbarch_info as it
is only passed by copy, not reference.

gdb/ChangeLog:

* s390-linux-tdep.c (gdbarch_tdep) <tdesc>: New field.
(s390_gdbarch_tdep_alloc): Adjust.
(s390_gdbarch_init): Adjust.

s390: gdbarch_tdep.have_* int -> bool

Currently the gdbarch_tdep.have_* flags are a mix of int and bool. Clean
this up by making them all bool.

gdb/ChangeLog:

* s390-linux-tdep.c (gdbarch_tdep) <have_linux_v1, have_linux_v2>
<have_tdb>: Change type to bool.
(s390_gdbarch_tdep_alloc): Adjust.
(s390_gdbarch_init): Adjust.

s390: Allocate gdbarch & tdep at start of gdbarch_init

Moving the allocation of gdbarch_tdep to the start of s390_gdbarch_init
allows us to use its fields for tracking the different features instead of
using separate variables. To make the code a little nicer move the actual
allocation and initialization to a separate function. Also move the
allocation of gdbarch to keep the two together.

gdb/ChangeLog:

* s390-linux-tdep (s390_abi_kind) <ABI_NONE>: New default field.
(gdbarch_tdep) <have_upper, have_vx>: New fields.
(s390_gdbarch_tdep_alloc): New function.
(s390_gdbarch_init): Allocate tdep at start and use its fields
instead of separate variables.

s390: Remove duplicate checks for cached gdbarch at init

When initializing the gdbarch there is a check whether an appropriate
gdbarch already exists in the gdbarch_list. Failing of some of the checks
would lead to a different target description. However
gdbarch_list_lookup_by_info already checks for

if (info->target_desc != arches->gdbarch->target_desc)
continue;

Remove these duplicate checks.

gdb/ChangeLog:

* s390-linux-tdep.c (s390_gdbarch_init): Remove duplicate checks
when looking for cached gdbarch and add comment for remaining.
