arm: Profile/variation detection improvements

Browse source 
* Detection of 64-bit Arm v8-a
 * Proper detection of integer division support
   * always on v7-m, v8-a, v9-a, v8-m.main
   * sometimes on v7-a, v7-r, v8-r
   * never on v8-m.base v6-m, v6 and older "classic"
   * tl;dr: Rely on toolchain preprocessor definition

For the most part these additional variations won't acutally work
for native target builds, but sane -A detection is needed for
"local" builds now. -R detection is left out as it's not likely
to matter.
