In structure CPUArchState some struct elements are only used in TCG
mode, and it is not used in KVM mode. Macro CONFIG_TCG is added to
make it simpiler in KVM mode, also there is the same modification
in c code when these structure elements are used.
When VM runs in KVM mode, TLB entries are not used and do not need
migrate. It is only useful when it runs in TCG mode.

With numa_test test case, there is subcase named test_def_cpu_split(),
there are 8 sockets and 2 numa nodes. Here is command line:
"-machine smp.cpus=8,smp.sockets=8 -numa node,memdev=ram -numa node"
The required result is:
node 0 cpus: 0 2 4 6
node 1 cpus: 1 3 5 7
Test case numa_test fails on LoongArch, since the actual result is:
node 0 cpus: 0 1 2 3
node 1 cpus: 4 5 6 7
It will be better if all the cpus in one socket share the same numa
node. Here socket id is used to calculate numa id in function
virt_get_default_cpu_node_id().

The old API took the size of the memory to duplicate as a guint,
whereas most memory functions take memory sizes as a gsize. This
made it easy to accidentally pass a gsize to g_memdup(). For large
values, that would lead to a silent truncation of the size from 64
to 32 bits, and result in a heap area being returned which is
significantly smaller than what the caller expects. This can likely
be exploited in various modules to cause a heap buffer overflow.
Replace g_memdup() by the safer g_memdup2() wrapper.
Trivially safe because the argument was directly from sizeof.

The fd: URI can currently trigger two different types of migration, a
TCP migration using sockets and a file migration using a plain
file. This is in conflict with the recently introduced (8.2) QMP
migrate API that takes structured data as JSON-like format. We cannot
keep the same backend for both types of migration because with the new
API the code is more tightly coupled to the type of transport. This
means a TCP migration must use the 'socket' transport and a file
migration must use the 'file' transport.
If we keep allowing fd: when using a file, this creates an issue when
the user converts the old-style (fd:) to the new style ("transport":
"socket") invocation because the file descriptor in question has
previously been allowed to be either a plain file or a socket.
To avoid creating too much confusion, we can simply deprecate the fd:
+ file usage, which is thought to be rarely used currently and instead
establish a 1:1 correspondence between fd: URI and socket transport,
and file: URI and file transport.

For hmp_migrate_incoming(), let's enable the new behavior: HMP is not

not to stop the process.
For x-exit-preconfig, let's keep the old behavior:

- it does exit on error by itself as well

Now that a bulk of opcodes go through the new decoder, it is sensible
to do some cleanup. Go immediately through disas_insn_new and only jump
back after parsing the prefixes.
disas_insn() now only contains the three sigsetjmp cases, and they
are more easily managed if they are inlined into i386_tr_translate_insn.

Split the bits that have some duplication with disas_insn_new, from
those that should be the main topic of the conversion. This is the
first step towards removing duplicate decoding of prefixes between
disas_insn and disas_insn_new.

These are unlikely to be converted to the table-based decoding
soon (perhaps there could be generic ESC decoding in decode-new.c.inc
for the Mod/RM byte, but not operand decoding), so keep them separate
from the remaining legacy-decoded instructions.
