Remove createNode() and any API that depending on it, and add
HasCreateNode to the list of checks for HasObsoleteCustomizations. Now
an ilist *never* allocates (this was already true for iplist).
This factors out all the differences between iplist and ilist. I'll aim
to rename both to "owning_ilist" eventually, to call out the interesting
(not exactly intrusive) ownership semantics. In the meantime, I've left
both names around to reduce code churn.
One of the deleted APIs is the ilist copy constructor. I've lifted up
and tested iplist::cloneFrom (ala simple_ilist::cloneFrom) as a
replacement.
Users of ilist<> and iplist<> that want the list to allocate nodes have
a few options:
- use std::list;
- use AllocatorList or BumpPtrList (or build a similarly trivial list);
- use cloneFrom (which is explicit at the call site); or
- allocate at the call site.
See r280573, r281177, r281181, and r281182 for examples of what to do if
you're updating out-of-tree code.

... and make a few ilist-internal API changes, in preparation for
changing how ilist_node is templated. The only effect for ilist users
should be changing the friend target from llvm::ilist_node_access to
llvm::ilist_detail::NodeAccess (which is only necessary when they
inherit privately from ilist_node).
- Split out SpecificNodeAccess, which has overloads of getNodePtr and
getValuePtr that are untemplated.
- Use more typedefs to prevent more changes later.
- Force inheritance to use *NodeAccess (to emphasize that ilist *users*
shouldn't be doing this).
There should be no functionality change here.

This test was using the wrong type, and so not actually testing much.
ilist_iterator constructors weren't going through ilist_node_access, so
they didn't actually work with private inheritance.

Many lists want to override only allocation semantics, or callbacks for
iplist. Split these up to prevent code duplication.
- Specialize ilist_alloc_traits to change the implementations of
deleteNode() and createNode().
- One common desire is to do nothing deleteNode() and disable
createNode(). Specialize ilist_alloc_traits to inherit from
ilist_noalloc_traits for that behaviour.
- Specialize ilist_callback_traits to use the addNodeToList(),
removeNodeFromList(), and transferNodesFromList() callbacks.
As a drive-by, add some coverage to the callback-related unit tests.

And rename the tests inside from ilistTest to IListTest. This makes the
file sort properly in the CMakeLists.txt (previously, sorting would
throw it down to the end of the list) and is consistent with the tests
I've added more recently.
Why use IListNodeBaseTest.cpp (and a test name of IListNodeBaseTest)?
- ilist_node_base_test is the obvious thing, since this is testing
ilist_node_base. However, gtest disallows underscores in test names.
- ilist_node_baseTest fails for the same reason.
- ilistNodeBaseTest is weird, because it isn't in our usual
TitleCaseTest form that we use for tests, and it also doesn't have the
name of the tested class in it.
- IlistNodeBaseTest matches TitleCaseTest, but "Ilist" is hard to read,
and really "ilist" is an abbreviation for "IntrusiveList" so the
lowercase "list" is strange.
- That left IListNodeBaseTest.
Note: I made this move in two stages, with a temporary filename of
ilistTestTemp in between in r279524. This was in the hopes of avoiding
problems on Git and SVN clients on case-insensitive filesystems,
particularly on buildbots with incremental checkouts.
