In preparation for FORTIFY_SOURCE performing compile-time and run-
time
field bounds checking for memcpy(), avoid intentionally writing
across
neighboring fields.
Use struct_group() in struct art around members weight, and ac[0-
9]_max,
so they can be referenced together. This will allow memcpy() and
sizeof()
to more easily reason about sizes, improve readability, and avoid
future
warnings about writing beyond the end of weight.
"pahole" shows no size nor member offset changes to struct art.
"objdump -d" shows no meaningful object code changes (i.e. only
source
line number induced differences).
