[gambit-list] Improved performance in b22

I ran "bench gambit all" in b20 and b22 (which tests r5rs semantics)  
and I find that, using the formula

( product of all beta 22 times / product of all beta 20 times) ^ (1/ 
number of tests)

I get .9577913077382927 on an otherwise unloaded 2GHz G5, so about 4%  
faster.  Not bad.  I get almost exactly the same in r6rs mode, . 

Perhaps you can have gsc generate ___EXPECT_TRUE and ___EXPECT_FALSE  
GVM expressions for the fixnum and flonum tests when (declare (mostly- 
fixnum-flonum) (run-time-bindings)).
