722272df41 Add two new classes: WeakVH and AssertingVH. These are both "ValueHandles",
which are effectively smart pointers to Value*'s.  They are both very light
weight and simple, and react to values being destroyed or being RAUW'd.

WeakVN does a best effort to follow a value around, including through RAUW 
operations and will get nulled out of the value is destroyed.  This is useful
for the eventual "metadata that references a value" work, because it is a
reference to a value that does not show up on its use_* list.

AssertingVH is a pointer that compiles down to a dumb raw pointer when 
assertions are disabled.  When enabled, it emits an assertion if the 
pointed-to value is destroyed while it is still being referenced.  This
is very useful for Maps and other things, and should have caught the recent
bugs in CallGraph and Reassociate, for example.

ae5a20a917 Rearrange operands of the BranchInst, to be able to
access each with a fixed negative index from op_end().

This has two important implications:
- getUser() will work faster, because there are less iterations
  for the waymarking algorithm to perform. This is important
  when running various analyses that want to determine callers
  of basic blocks.
- getSuccessor() now runs faster, because the indirection via OperandList
  is not necessary: Uses corresponding to the successors are at fixed
  offset to "this".

The price we pay is the slightly more complicated logic in the operator
User::delete, as it has to pick up the information whether it has to free
the memory of an original unconditional BranchInst or a BranchInst that
was originally conditional, but has been shortened to unconditional.
I was not able to come up with a nicer solution to this problem. (And
rest assured, I tried *a lot*).

Similar reorderings will follow for InvokeInst and CallInst. After that
some optimizations to pred_iterator and CallSite will fall out naturally.

5d0392c6b3 Factorize code: remove variants of "strip off
pointer bitcasts and GEP's", and centralize the
logic in Value::getUnderlyingObject.  The
difference with stripPointerCasts is that
stripPointerCasts only strips GEPs if all
indices are zero, while getUnderlyingObject
strips GEPs no matter what the indices are.

This patch replaces the SymbolTable class with ValueSymbolTable which does
not support types planes. This means that all symbol names in LLVM must now
be unique. The patch addresses the necessary changes to deal with this and
removes code no longer needed as a result. This completes the bulk of the
changes for this PR. Some cleanup patches will follow.

04cb800c32 This fixes PR531, a crash when running the CBE on a bytecode file.
The problem is that Function::renameLocalSymbols is iterating through
the symbol table planes, occasionally calling setName to rename a value
(which used to do a symbol table remove/insert pair).

The problem is that if there is only a single value in a particular type
plane that the remove will nuke the symbol table plane, and the insert
will create and insert a new one.  This hoses Function::renameLocalSymbols
because it has an iterator to the old plane, under the (very reasonable)
assumption that simply renaming a value won't cause the type plane to
disappear.

This patch fixes the bug by making the rename operation a single atomic
operation, which has a side effect of making the whole thing faster too. :)

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/.

c3cc71abbc Completely rewrite support for the Value::use_* list. Now, all operations on
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.

and make Value contain a PATypeHolder.
