c53eed1703 Change lemon so that it does not generate yytestcase() macros on destructor 
cases since destructors are commonly unreachable in a reasonable grammar.
For the reduce-rule switch, gather all no-ops into the "default:" case. (CVS 6757)

8a415d3743 The lemon parser generator now inserts yytestcase() macros on reduce action 
and on each destructor, to verify that all have been executed.  yytestcase()
is a no-op by default but can be set to something more useful inside
of %include. (CVS 6755)
