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.

Fix an issue where assignments that caused a SmallPtrSet to become non-small

would result in calling realloc() on a null pointer. Instead, if we encounter
this situation, make a normal call to malloc().

Two changes:
...
1. Make SmallPtrSet::erase faster in the small case by replacing a memmove
with a pointer copy.
2. Fix a bug where the null terminator at the end of the array in the small
case was not copied
