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).

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 a bug in the densemap that was killing the local allocator, and probably
...
other clients. The problem is that the nullVal member was left to the default
constructor to initialize, which for int's does nothing (ie, leaves it unspecified).
To get a zero value, we must use T(). It's C++ wonderful? :)
