Summary: simple "is" speedup 

Initial Comment:
All this "is" vs "==" discussion led me to look at ceval.c.  
The attached patch seems to speed up "is" and "is not" 
comparisons - saving a function call to do a simple pointer 
comparison for non-integer arguments.

The test suite passes, but it's been quite awhile since I 
messed around with the interpreter code, so I thought I 
ought to have another pair of eyeballs check it out...
