  tcg: Fix register move type in tcg_out_ld_helper_ret

The first move was incorrectly using TCG_TYPE_I32 while the second
move was correctly using TCG_TYPE_REG.  This prevents a 64-bit host
from moving all 128-bits of the return value.

  meson: Split test for __int128_t type from __int128_t arithmetic

Older versions of clang have missing runtime functions for arithmetic
with -fsanitize=undefined (see 464e3671f9d5c), so we cannot use
__int128_t for implementing Int128.  But __int128_t is present,
data movement works, and it can be used for atomic128.

Probe for both CONFIG_INT128_TYPE and CONFIG_INT128, adjust
qemu/int128.h to define Int128Alias if CONFIG_INT128_TYPE,
and adjust the meson probe for atomics to use has_int128_type.

  docs: Document decodetree named field syntax

Document the named field syntax that we want to implement for the
decodetree script.  This allows a field to be defined in terms of
some other field that the instruction pattern has already set, for
example:

   %sz_imm 10:3 sz:3 !function=expand_sz_imm

to allow a function to be passed both an immediate field from the
instruction and also a sz value which might have been specified by
the instruction pattern directly (sz=1, etc) rather than being a
simple field within the instruction.

Note that the restriction on not having the format referring to the
pattern and the pattern referring to the format simultaneously is a
restriction of the decoder generator rather than inherently being a
silly thing to do.

  scripts/decodetree: Pass lvalue-formatter function to str_extract()

To support referring to other named fields in field definitions, we
need to pass the str_extract() method a function which tells it how
to emit the code for a previously initialized named field.  (In
Pattern::output_code() the other field will be "u.f_foo.field", and
in Format::output_extract() it is "a->field".)

Refactor the two callsites that currently do "output code to
initialize each field", and have them pass a lambda that defines how
to format the lvalue in each case.  This is then used both in
emitting the LHS of the assignment and also passed down to
str_extract() as a new argument (unused at the moment, but will be
used in the following patch).

  scripts/decodetree: Implement a topological sort

To support named fields, we will need to be able to do a topological
sort (so that we ensure that we output the assignment to field A
before the assignment to field B if field B refers to field A by
name). The good news is that there is a tsort in the python standard
library; the bad news is that it was only added in Python 3.9.

To bridge the gap between our current minimum supported Python
version and 3.9, provide a local implementation that has the
same API as the stdlib version for the parts we care about.
In future when QEMU's minimum Python version requirement reaches
3.9 we can delete this code and replace it with an 'import' line.

The core of this implementation is based on
https://code.activestate.com/recipes/578272-topological-sort/
which is MIT-licensed.

  scripts/decodetree: Implement named field support

Implement support for named fields, i.e.  where one field is defined
in terms of another, rather than directly in terms of bits extracted
from the instruction.

The new method referenced_fields() on all the Field classes returns a
list of fields that this field references.  This just passes through,
except for the new NamedField class.

We can then use referenced_fields() to:
 * construct a list of 'dangling references' for a format or
   pattern, which is the fields that the format/pattern uses but
   doesn't define itself
 * do a topological sort, so that we output "field = value"
   assignments in an order that means that we assign a field before
   we reference it in a subsequent assignment
 * check when we output the code for a pattern whether we need to
   fill in the format fields before or after the pattern fields, and
   do other error checking

  tests/decode: Add tests for various named-field cases

Add some tests for various cases of named-field use, both ones that
should work and ones that should be diagnosed as errors.

  tests/avocado/virtio-gpu: Cancel test if drm rendering is not available

The test_vhost_user_vga_virgl test currently fails on some CI
machines with:

 qemu-system-x86_64: egl: no drm render node available
 qemu-system-x86_64: egl: render node init failed

The other test in this file already checks whether there is
an error while starting QEMU - we should do the same for the
test_vhost_user_vga_virgl test, too.
