Bug #19764: SHOW commands end up in the slow log as table scans

Browse Source 
Do not consider SHOW commands slow queries, just because they don't use proper indexes.

This bug fix is not needed in 5.1, and the code changes will be null merged.  However, the test cases will be propogated up to 5.1.
