Reuse a technique (pioneered for BasicBlocks) of superposing ilist with

its sentinel. This is quite a win when a function really has a basic block.
When the function is just a declaration (and stays so) the old way did not
allocate a sentinel. So this change is most beneficial when the ratio of
function definition to declaration is high. I.e. linkers etc. Incidentally
these are the most resource demanding applications, so I expect that the
reduced malloc traffic, locality and space savings outweigh the cost of
addition of two pointers to Function.

Fix a long-standing bug and misfeature of the disassembler: when dealing with a
...
stripped .bc file, it didn't make any attempt to try to reuse anonymous types.
This causes an amazing type explosion due to types getting duplicated everywhere
they are referenced and other problems.
This also caused correctness issues, because opaque types are unique for each time
they are uttered in the file. This means that stripping a .bc file could produce
a .ll file that could not be assembled (e.g. 2009-02-28-StripOpaqueName.ll).
This patch fixes both of these issues.
