Update our copy of libvixl to upstream's 1.7 release.
This includes upstream's fix for the issue we had a local
patch for in commit 94cc44a9e.

The instructions-a64.h header defines a number of floating point
constants whose initializers are function calls. gcc 5 will warn
if these constants are not used by the C or C++ file which includes
the header, because they imply a runtime cost. Since for the files
QEMU uses from libvixl we don't use these constants at all, just
remove them.
Upstream intend to fix these by shifting to an 'extern const' in
the header plus definition in a suitable source file, so we can
drop this patch when we sync with the upcoming libvixl 1.7.

Update our copy of libvixl to upstream 1.6. There are no
changes of any particular interest to QEMU, so this is simply
keeping up with current upstream.

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.

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.
