755aceb5d0 Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static 
ID member as the sole unique type identifier.  Clean up APIs related to this change.

3cdae269f0 While DAE can't modify the function signature of an externally visible function, 
it can check whether the visible direct callers are passing in parameters to
dead arguments and replace those with undef.

This reinstates r94322 with bugs fixed.

4568ed7893 Implement support for varargs functions without any fixed 
parameters in the CBE by implicitly adding a fixed argument.
This allows eliminating a work-around from DAE.  Patch by

5d5db5342b Introduce ImmutableCallSite, useful for contexts where no mutation 
is necessary. Inherits from new templated baseclass CallSiteBase<>
which is highly customizable. Base CallSite on it too, in a configuration
that allows full mutation.
Adapt some call sites in analyses to employ ImmutableCallSite.

a2fbc0ae1b Finally land the InvokeInst operand reordering. 
I have audited all getOperandNo calls now, fixing
hidden assumptions. CallSite related uglyness will
be eliminated successively.

Note this patch has a long and griveous history,
for all the back-and-forths have a look at
CallSite.h's log.

8335f9c0bf Recommit r80858 again (which has been backed out in r80871). 
This time I did a self-hosted bootstrap on Linux x86-64,
with no problems. Let's see how darwin 64-bit self-hosting
goes. At the first sign of failure I'll back this out.

Maybe the valgrind bots give me a hint of what may be wrong
(it at all).

19d0b47b1f There are two ways of checking for a given type, for example isa<PointerType>(T) 
and T->isPointerTy().  Convert most instances of the first form to the second form.

0dd5e1ed39 More migration to raw_ostream, the water has dried up around the iostream hole. 
- Some clients which used DOUT have moved to DEBUG. We are deprecating the
   "magic" DOUT behavior which avoided calling printing functions when the
   statement was disabled. In addition to being unnecessary magic, it had the
   downside of leaving code in -Asserts builds, and of hiding potentially
   unnecessary computations.

258232fb80 Second installment of "BasicBlock operands to the back" 
changes.

For InvokeInst now all arguments begin at op_begin().
The Callee, Cont and Fail are now faster to get by
access relative to op_end().

This patch introduces some temporary uglyness in CallSite.
Next I'll bring CallInst up to a similar scheme and then
the uglyness will magically vanish.

This patch also exposes all the reliance of the libraries
on InvokeInst's operand ordering. I am thinking of taking
care of that too.
