  -----------
  [clang][driver] Allow unaligned access on ARMv7 and higher by default (#82400)

ARM's Clang and GCC embedded compilers default to allowing unaligned
access for ARMv7+. This patch changes the Clang driver default to match.
Users can opt out with `-mno-unaligned-access`.

Fixes #59560
