This list does not provide the ability to go backwards in the list (its
more of an unordered collection, stored in the shape of a list).
This change means that use iterators are now only forward iterators, not
bidirectional.
This improves the memory usage of use lists from '5 + 4*#use' per value to
'1 + 4*#use'. While it would be better to reduce the multiplied factor,
I'm not smart enough to do so. This list also has slightly more efficient
operators for manipulating list nodes (a few less loads/stores), due to not
needing to be able to iterate backwards through the list.
This change reduces the memory footprint required to hold 176.gcc from
66.025M -> 57.687M, a 14% reduction. It also speeds up the compiler,
7.73% in the case of bytecode loading alone (release build loading 176.gcc).

Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

- Add ValueListTy to TypeTy so that the bcreader can have its own User
category that won't get factored into any optimizations or cleanup.
- Correct an isa_impl to correctly include GlobalValue now that it isa
Constant.

now send references to ostreams instead of pointers. Sending pointers to
ostreams will print their addresses.

- Remove isa_impl relationship between Types and Values
- Add OtherVal so "other" users can interact with Values.

This reduces the size of the instruction class by 4 bytes, and means that
isa<CallInst>(V) (for example) only needs to do one load from memory instead
of two.

symbols with. Therefore, if you do not use struct/class consistently, you can
get LINK ERRORS. grr.
This fixes the link errors for libsupport and vmcore.

all dynamically allocated LLVM values 4 bytes smaller, eliminate some vtables, and
make Value's destructor faster.
This makes Function derive from Annotation now because it is the only core LLVM
class that still has an annotation stuck onto it: MachineFunction.
MachineFunction is obviously horrible and gross (like most other annotations), but
will be the subject of refactorings later in the future. Besides many fewer
Function objects are dynamically allocated that instructions blocks, constants,
types, etc... :)

this list (except use_size()) are constant time. Before the killUse method
(used whenever something stopped using a value) was linear time, and thus
very very slow for large programs.
This speeds GCCAS up _substantially_ on large programs: almost 2x for 176.gcc:
176.gcc: 77.07s -> 37.38s
177.mesa: 7.59s -> 5.57s
252.eon: 21.02s -> 19.52s (*)
253.perlbmk: 11.40s -> 13.05s
254.gap: 7.25s -> 7.42s
252.eon would speed up a whole lot more, but optimization time is being
dominated by the inlining pass, which needs to be fixed.

significantly more complete. Instead, just make DerivedType's AbstractTypeUser's,
and make Value contain a PATypeHolder. This will also be more efficient in the
future.

* Add top level virtual print function, disallows instantiating Value's
directly.
* Provide operator<< for values here, instead of in Assembly/Writer.h
