If you build QEMU with the clang sanitizer enabled, you can see it
fire when running the arm-cpu-features test:
$ QTEST_QEMU_BINARY=./build/arm-clang/qemu-system-aarch64 ./build/arm-clang/tests/qtest/arm-cpu-features
[...]
../../target/arm/cpu64.c:125:19: runtime error: shift exponent 64 is too large for 64-bit type 'unsigned long long'
[...]
This happens because the user can specify some incorrect SVE
properties that result in our calculating a max_vq of 0. We catch
this and error out, but before we do that we calculate
vq_mask = MAKE_64BIT_MASK(0, max_vq);$
and the MAKE_64BIT_MASK() call is only valid for lengths that are
greater than zero, so we hit the undefined behaviour.
Change the logic so that if max_vq is 0 we specifically set vq_mask
to 0 without going via MAKE_64BIT_MASK(). This lets us drop the
max_vq check from the error-exit logic, because if max_vq is 0 then
vq_map must now be 0.
The UB only happens in the case where the user passed us an incorrect
set of SVE properties, so it's not a big problem in practice.

We already squash the ID register field for FEAT_SPE (the Statistical
Profiling Extension) because TCG does not implement it and if we
advertise it to the guest the guest will crash trying to look at
non-existent system registers. Do the same for some other features
which a real hardware Neoverse-V1 implements but which TCG doesn't:
* FEAT_TRF (Self-hosted Trace Extension)
* Trace Macrocell system register access
* Memory mapped trace
* FEAT_AMU (Activity Monitors Extension)
* FEAT_MPAM (Memory Partitioning and Monitoring Extension)
* FEAT_NV (Nested Virtualization)
Most of these, like FEAT_SPE, are "introspection/trace" type features
which QEMU is unlikely to ever implement. The odd-one-out here is
FEAT_NV -- we could implement that and at some point we probably
will.

Unlike architectures with precise self-modifying code semantics
(e.g. x86) ARM processors do not maintain coherency for instruction
execution and memory, requiring an instruction synchronization
barrier on every core that will execute the new code, and on many
models also the explicit use of cache management instructions.
While this is required to make JITs work on actual hardware, QEMU
has gotten away with not handling this since it does not emulate
caches, and unconditionally invalidates code whenever the softmmu
or the user-mode page protection logic detects that code has been
modified.
Unfortunately the latter does not work in the face of dual-mapped
code (a common W^X workaround), where one page is executable and
the other is writable: user-mode has no way to connect one with the
other as that is only known to the kernel and the emulated
application.
This commit works around the issue by telling software that
instruction cache invalidation is required by clearing the
CPR_EL0.DIC flag (regardless of whether the emulated processor
needs it), and then invalidating code in IC IVAU instructions.

The lack of SVE memory instrumentation has been an omission in plugin

It will be helpful to have ARMMMUIdx_Phys_* to be in the same
relative order as ARMSecuritySpace enumerators. This requires
the adjustment to the nstable check. While there, check for being
in secure state rather than rely on clearing the low bit making
no change to non-secure state.

With RME, SEL2 must also be present to support secure state.
The NS bit is RES1 if SEL2 is not present.

Add the missing field for ID_AA64PFR0, and the predicate.
Disable it if EL3 is forced off by the board or command-line.

We use the user_ss[] array to hold the user emulation sources,
and the softmmu_ss[] array to hold the system emulation ones.
Hold the latter in the 'system_ss[]' array for parity with user
emulation.
Mechanical change doing:
$ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss)
