Only clear the JIT function when we invalidate the entry block

Browse source 
We should only clear the JIT function when the entry point is
invalidated.  Right now we only support compiling functions with a PC
offset of zero (functions that take optional parameters can start at
non-zero PC), so this patch just checks that the index is 0 before
clearing the jit function
