The element size is located in m5, not in m4. As there is no m4, qemu
currently crashes with an assertion, trying to lookup that field.
Reproduced and tested via GO, which ends up using VMSL once the
Vector enhancements facility is around for verifying certificates with
elliptic curves.

The FP-to-integer conversion instructions need to set CC 3 whenever
a "special case" occurs; this is the case whenever the instruction
also signals the IEEE invalid exception. (See e.g. figure 19-18
in the Principles of Operation.)
However, qemu currently will set CC 3 only in the case where the
input was a NaN. This is indeed one of the special cases, but
there are others, most notably the case where the input is out
of range of the target data type.
This patch fixes the problem by switching these instructions to
the "static" CC method and computing the correct result directly
in the helper. (It cannot be re-computed later as the information
about the invalid exception is no longer available.)
This fixes a bug observed when running the wasmtime test suite
under the s390x-linux-user target.

Switch from QemuOpts to keyval. This enables the introduction
of non-scalar machine properties, and JSON syntax in the future.
For JSON syntax to be supported right now, we would have to
consider what would happen if string-based dictionaries (produced by
-M key=val) were to be merged with strongly-typed dictionaries
(produced by -M {'key': 123}).
The simplest way out is to never enter the situation, and only allow one
-M option when JSON syntax is in use. However, we want options such as
-smp to become syntactic sugar for -M, and this is a problem; as soon
as -smp becomes a shortcut for -M, QEMU would forbid using -M '{....}'
together with -smp. Therefore, allowing JSON syntax right now for -M
would be a forward-compatibility nightmare and it would be impossible
anyway to introduce -M incrementally in tools.
Instead, support for JSON syntax is delayed until after the main
options are converted to QOM compound properties. These include -boot,
-acpitable, -smbios, -m, -semihosting-config, -rtc and -fw_cfg. Once JSON
syntax is introduced, these options will _also_ be forbidden together
with -M '{...}'.

As with previous performance optimization on Treaddir handling;
reduce the overall latency, i.e. overall time spent on processing
a Twalk request by reducing the amount of thread hops between the
9p server's main thread and fs worker thread(s).
In fact this patch even reduces the thread hops for Twalk handling
to its theoritical minimum of exactly 2 thread hops:
main thread -> fs worker thread -> main thread
This is achieved by doing all the required fs driver tasks altogether
in a single v9fs_co_run_in_worker({ ... }); code block.
