Title:
  qemu-arm should accept vmrs apsr_nzcv, fpscr on M-profile

Status in QEMU:
  Fix Released

Bug description:
  I've noticed that qemu-arm for cortex-M considers
  vmrs apsr_nzcv, fpscr
  as an illegal instruction.

  In this case, rt==15 means APSR, and the instruction should be
  accepted and executed like for A-profile.

  I posted a small patch:
