For compiling with -Wimplicit-fallthrough we need to fix the
fallthrough annotations in the libvixl code. This is based on
the following upstream vixl commit by Martyn Capewell:
https://git.linaro.org/arm/vixl.git/commit/?id=de326f850f736c3a337
"GCC 7 enables switch/case fallthrough checking, but this fails in
VIXL, because the annotation we use is Clang specific.
Also, fix a missing annotation in the disassembler."
