History
Chris Lattner 42e4bdf257 When clearing a SmallPtrSet, if the set had a huge capacity, but the 
contents of the set were small, deallocate and shrink the set.  This
avoids having us to memset as much data, significantly speeding up
some pathological cases.  For example, this speeds up the verifier
from 0.3899s to 0.0763 (5.1x) on the testcase from PR1432 in a 
release build.
