TILE-Gx was only implemented in linux-user mode, but support for this CPU
was removed from the upstream Linux kernel in 2018, and it has also been
dropped from glibc, so there is no new Linux development taking place with
this architecture. For running the old binaries, users can simply use older
versions of QEMU.

The Clock framework allows users to specify a callback which is
called after the clock's period has been updated. Some users need to
also have a callback which is called before the clock period is
updated.
As the first step in adding support for notifying Clock users on
pre-update events, add an argument to the ClockCallback to specify
what event is being notified, and add an argument to the various
functions for registering a callback to specify which events are
of interest to that callback.
Note that the documentation update renders correct the previously
incorrect claim in 'Adding a new clock' that callbacks "will be
explained in a following section".

Section D6.7 of the ARM ARM states:
For the purpose of determining Tag Check Fault handling, unprivileged
load and store instructions are treated as if executed at EL0 when
executed at either:
- EL1, when the Effective value of PSTATE.UAO is 0.
- EL2, when both the Effective value of HCR_EL2.{E2H, TGE} is {1, 1}
and the Effective value of PSTATE.UAO is 0.
ARM has confirmed a defect in the pseudocode function
AArch64.TagCheckFault that makes it inconsistent with the above
wording. The remedy is to adjust references to PSTATE.EL in that
function to instead refer to AArch64.AccessUsesEL(acctype), so
that unprivileged instructions use SCTLR_EL1.TCF0 and TFSRE0_EL1.
The exception type for synchronous tag check faults remains unchanged.
This patch implements the described change by partially reverting
commits 50244cc76a and cc97b0019b.

Always perform one call instead of two for 16-byte operands.
Use byte loads/stores directly into the vector register file
instead of extractions and deposits to a 64-bit local variable.
In order to easily receive pointers into the vector register file,
convert the helper to the gvec out-of-line signature. Move the
helper into vec_helper.c, where it can make use of H1 and clear_tail.

There is a compiler warning with GCC 9.3 when compiling with
the -fsanitize=thread compiler flag:
In function 'strncpy',
inlined from 's390x_write_elf64_notes' at ../target/s390x/arch_dump.c:219:9:
/usr/include/x86_64-linux-gnu/bits/string_fortified.h:106:10: error:
'__builtin_strncpy' specified bound 8 equals destination size
[-Werror=stringop-truncation]
Since the name should always be NUL-terminated, let's use g_strlcpy() to
silence this warning. And while we're at it, also add an assert() to make
sure that the provided names always fit the size field (which is fine for
the current callers, the function is called once with "CORE" and once with
"LINUX" as a name).

Secure execution (aka protected virtualization) guests cannot be
migrated at the moment. If the unpack facility is provided in the cpu
model, a guest may choose to transition to secure mode, making the
guest unmigratable at that point in time. If the machine was explicitly
started with --only-migratable, we would get a failure only when the
guest actually tries to transition; instead, explicitly disallow the
unpack facility if --only-migratable was specified to avoid late
surprises.

Bus lock debug exception is a feature that can notify the kernel by
generate an #DB trap after the instruction acquires a bus lock when
CPL>0. This allows the kernel to enforce user application throttling or
mitigations.
This feature is enumerated via CPUID.(EAX=7,ECX=0).ECX[bit 24].

The cpu::mmr[] array contains the upper halves of 128-bit GPR
registers. While they are only used by the R5900 CPU, the
concept is generic and could be used by another MIPS implementation.
Rename 'cpu::mmr' as 'cpu::gpr_hi' and make them global.
When the code is similar to the GPR lower halves, move it
close by.
