This patch also appears to fix Evan's reported problem supplied as a
reduced bugpoint test case.

retain/release checker: Implement basic tracking of autorelease stack.  Next thing is to wire up pools with their contents.

array type, not pointer type.

external declarations to also support external variable
declarations. Unified the code for these two cases into two new
subroutines.

Note that we fail to diagnose cases like the one Neil pointed
out, where a visible non-external declaration hides an external
declaration by the same name. That will require some reshuffling of
name lookup.

- For autorelease pool tracking, keep information about the stack of pools
  separate from their contents. Also, keep track of the number of times an
  autorelease pool will send the "release" message to an object when the pool is
  destroyed.
- Update CFRefCount::Update to return a new state instead of a reference count
  binding. This will allow us to implement more complicated semantics with
  autorelease pools.

to describe what the backedge-taken count is and how it differs
from the actual iteration count of the loop. Adjust names and
comments in associated code accordingly.
