    Fix save/restore of contexts which have pending exceptions · 48d821ca

    Detail:
      s/Module - Fixed context save & restore code to ensure FPEXC EX & FP2V bits are clear when accessing FPSCR and the main VFP registers. Without doing this, attempting to save or restore a context which has a pending exception will trigger an exception itself.
      Test/test2,ffb - Simple test to make sure save/restore of contexts with pending exceptions works properly
      Test/test1,ffb - Added brief description, changed file from plain text to tokenised BASIC to prevent it accidentally happening later on

      Tested on Raspberry Pi
      Programs which need support code to run or trigger math exceptions no longer trigger an undefined instruction abort from within VFPSupport
