f341a47d10 When forming sentinels for empty/tombstone, make sure to respect the 
pointer's expected number of zero low-bits.

This should fix the breakage I introduced recently.

aef806e9cb Added typedef "value_type" to DenseMap (similar typedef appears in std::map). 
Added method FindAndConstruct() to DenseMap, which does the same thing as
operator[], except that it refers value_type& (a reference to both the
key and mapped data pair).  This method is useful for clients that wish
to access the stored key value, as opposed to the key used to do the
actual lookup (these need not always be the same).

Redefined operator[] to use FindAndConstruct() (same logic).

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.
