Currently the Makefile of disas/libvixl appends
-I$(SRC_PATH)/disas/libvixl to QEMU_CFLAGS. As a consequence C++ files
that #include "utils.h", such as disas/libvixl/a64/instructions-a64.cc,
are going to look for utils.h on all the other include paths first.
When building QEMU as part of the Xen make system, another unrelated
utils.h file is going to be chosen for inclusion, causing a build
failure:
In file included from disas/libvixl/a64/instructions-a64.cc:27:0:
/qemu/disas/libvixl/a64/instructions-a64.h:88:64: error:
'rawbits_to_float' was not declared in this scope
const float kFP32PositiveInfinity = rawbits_to_float(0x7f800000);
Fix the problem by prepending (rather than appending) the libvixl
include path to QEMU_CFLAGS.

When the compiler is told to check the arguments of AppendToOutput,
it reports several errors of this kind:
error: format ‘%d’ expects argument of type ‘int’,
but argument 3 has type ‘int64_t {aka long int}’ [-Werror=format]
Fix those bugs by using the correct format strings with PRId64, PRIx64.

Update our copy of libvixl to upstream's 1.4 release.
Note that we no longer need any local fixes for compilation
on 32 bit hosts -- they have all been integrated upstream.

disas: Implement disassembly output for A64
Use libvixl to implement disassembly output in debug
logs for A64, for use with both AArch64 hosts and targets.
disas/libvixl/ contains functions which uses 64bit constants
without using appropriate suffixes, which fails on 32bits.
Fix this by using ULL suffix.

[PMM:
* added support for target disassembly
* switched to custom QEMUDisassembler so the output format
matches what QEMU expects
* make sure we correctly fall back to "just print hex"
if we didn't build the AArch64 disassembler because of
lack of a C++ compiler
* rename from 'aarch64' to 'arm-a64' because this is a
disassembler for the A64 instruction set
* merge aarch64.c and aarch64-cxx.cc into one C++ file
* simplify the aarch64.c<->aarch64-cxx.cc interface]

Fix various minor issues with upstream libvixl so that it will compile
successfully on the platforms QEMU cares about:
* remove unused GBytes constant (it clashes with the glib headers)
* fix suffixes on constants to use 'LL' for 64 bit constants so
we can compile on 32 bit hosts

Add the subset of the libvixl sources that are needed for the
A64 disassembler support. These sources come from
https://github.com/armvixl/vixl commit 578645f14e122d2b
which is VIXL release 1.1.
