This fixes resizing issues with BitVectors. It ensures that the BitWord type and type size is always used, and ensures completely correct clearing of unused high bits, and setting of bits when resizing. It should resolve PR1563.

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.

already covered by getLowBitsSet (i.e. when loBits==0). Consequently, remove

Added an automatic cast to "std::ostream*" etc. from OStream. We then can
...
rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.

Change the implementation of statistic to not need destructors at all.
...
Instead, the stat info is printed when llvm_shutdown() is called.
These also don't need static ctors, but getting rid of them is uglier:
still investigating. This reduces the number of static dtors in llvm from
~1400 to ~750.
