Sprinkle some PrettyStackEntry magic into the passmanager. With this, we now

get nice and happy stack traces when we crash in an optimizer or codegen. For
example, an abort put in UnswitchLoops now looks like this:
Stack dump:
0. Program arguments: clang pr3399.c -S -O3
1. <eof> parser at end of file
2. per-module optimization passes
3. Running pass 'CallGraph Pass Manager' on module 'pr3399.c'.
4. Running pass 'Loop Pass Manager' on function '@foo'
5. Running pass 'Unswitch loops' on basic block '%for.inc'
Abort

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.

pic | !declaration | external | hidden | X | local dynamic
!pic | declaration | internal | default | tls5.ll tls6.ll | local exec
