Tests that an earlier bug does not occur. The issue was that the loading of the TLAB 'top' and 'end' values was being GVN'ed from each branch of the 'if' statement. This meant that the allocated B object in the true branch overwrote the allocated array. The cause is that RegisterNode was a floating node and the reads from it were UnsafeLoads which are also floating. The fix was to make RegisterNode a fixed node (which it should have been in the first place).
