We forgot a space in some log messages, so the output ended
up looking like
gicv3_dist_write: invalid guest write at offset 0000000000008000size 8

The GICv3 has some registers that support byte accesses, and some
that support 8-byte accesses. Our TCG implementation implements all
of this, switching on the 'size' argument and handling the registers
that must support reads of that size while logging an error for
attempted accesses to registers that do not support that size access.
However we forgot to tell the core memory subsystem about this by
specifying the .impl and .valid fields in the MemoryRegionOps struct,
so the core was happily simulating 8 byte accesses by combining two 4
byte accesses. This doesn't have much guest-visible effect, since
there aren't many 8 byte registers and they all support being written
in two 4 byte parts.
Set the .impl and .valid fields to say that all sizes from 1 to 8
bytes are both valid and implemented by the device.

For VLD3 (single 3-element structure to one lane), there is no
alignment specification and the alignment bits in the instruction
must be zero. This is bit [4] for the size=0 and size=1 cases, and
bits [5:4] for the size=2 case. We do this check correctly in
VLDST_single(), but we write it a bit oddly: in the 'case 3' code we
check for bit 0 of a->align (bit [4] of the insn), and then we fall
through to the 'case 2' code which checks bit 1 of a->align (bit [5]
of the insn) in the size 2 case. Replace this with just checking "is
a->align non-zero" for VLD3, which lets us drop the fall-through and
put the cases in this switch in numerical order.

For VLD1/VST1 (single element to one lane) we are only accessing one
register, and so the 'stride' is meaningless. The bits that would
specify stride (insn bit [4] for size=1, bit [6] for size=2) are
specified to be zero in the encoding (which would correspond to a
stride of 1 for VLD2/VLD3/VLD4 etc), and we must UNDEF if they are
not.
We failed to make this check, which meant that we would incorrectly
handle some instruction patterns as loads or stores instead of
UNDEFing them. Enforce that stride == 1 for the nregs == 1 case.

Currently we incorrectly think that posix_memalign() exists on
Windows. This is because of a combination of:
* the msys2/mingw toolchain/libc claim to have a
__builtin_posix_memalign when there isn't a builtin of that name
* meson will assume that if you have a __builtin_foo that
counts for has_function('foo')
Specifying a specific include file via prefix: causes meson to not
treat builtins as sufficient and actually look for the function
itself; see this meson pull request which added that as the official
way to get the right answer:
https://github.com/mesonbuild/meson/pull/1150
Currently this misdectection doesn't cause problems because we only
use CONFIG_POSIX_MEMALIGN in oslib-posix.c; however that will change
in a following commit.

Currently qemu_try_memalign()'s behaviour if asked to allocate
0 bytes is rather variable:
* on Windows, we will assert
* on POSIX platforms, we get the underlying behaviour of
the posix_memalign() or equivalent function, which may be
either "return a valid non-NULL pointer" or "return NULL"
Explictly check for 0 byte allocations, so we get consistent
behaviour across platforms. We handle them by incrementing the size
so that we return a valid non-NULL pointer that can later be passed
to qemu_vfree(). This is permitted behaviour for the
posix_memalign() API and is the most usual way that underlying
malloc() etc implementations handle a zero-sized allocation request,
because it won't trip up calling code that assumes NULL means an
error. (This includes our own qemu_memalign(), which will abort on
NULL.)
This change is a preparation for sharing the qemu_try_memalign() code
between Windows and POSIX.

We implement qemu_memalign() in both oslib-posix.c and oslib-win32.c,
but the two versions are essentially the same: they call
qemu_try_memalign(), and abort() after printing an error message if
it fails. The only difference is that the win32 version prints the
GetLastError() value whereas the POSIX version prints
strerror(errno). However, this is a bug in the win32 version: in
commit dfbd0b873a in 2020 we changed the implementation of
qemu_try_memalign() from using VirtualAlloc() (which sets the
GetLastError() value) to using _aligned_malloc() (which sets errno),
but didn't update the error message to match.
Replace the two separate functions with a single version in a
new memalign.c file, which drops the unnecessary extra qemu_oom_check()
function and instead prints a more useful message including the
requested size and alignment as well as the errno string.

Based on GCC docs[1], we use the '-mpower8-vector' flag at config-time
to detect the toolchain support to the bcdsub instruction. LLVM/Clang
supports this flag since version 3.6[2], but the instruction and related
builtins were only added in LLVM 14[3]. In the absence of other means to
detect this support at config-time, we resort to __has_builtin to
identify the presence of __builtin_bcdsub at compile-time. If the
builtin is not available, the instruction is emitted with a ".long".
