7103261: crash with jittester on sparc

The changes for 6985015 rearranged the logic for recording implicit
exceptions but save the offset of the faulting instruction twice
instead of just for the first one.  This means the implicit exception
is in on the second instruction instead of the first.  The original
test was very complicated so I wrote a simpler one that exercises all
the implicit null for fields.
