Mark Johnston f115c06121 amd64: Add MD bits for KASAN
- Initialize KASAN before executing SYSINITs.
- Add a GENERIC-KASAN kernel config, akin to GENERIC-KCSAN.
- Increase the kernel stack size if KASAN is enabled.  Some of the
  ASAN instrumentation increases stack usage and it's enough to
  trigger stack overflows in ZFS.
- Mark the trapframe as valid in interrupt handlers if it is
  assigned to td_intr_frame.  Otherwise, an interrupt in a function
  which creates a poisoned alloca region can trigger false positives.
