Remove SHAPE_MAX_NUM_IVS

There is no longer a limit on the number of IVs you can store.
SHAPE_MAX_NUM_IVS was used to work around the IV10K problem (the well
known problem where setting 10k instance variables in a row would be too
slow).  The redblack tree works well at any shape depth, even depths
greater than 80, and solves the IV10K problem.
