a541b0fde2 Change CallGraphNode to maintain it's Function as an AssertingVH 
for sanity.  This didn't turn up any bugs.

Change CallGraphNode to maintain its "callsite" information in the 
call edges list as a WeakVH instead of as an instruction*.  This fixes
a broad class of dangling pointer bugs, and makes CallGraph have a number
of useful invariants again.  This fixes the class of problem indicated
by PR4029 and PR3601.

58cfa3b137 Rename Instruction::isIdenticalTo to Instruction::isIdenticalToWhenDefined, 
and introduce a new Instruction::isIdenticalTo which tests for full
identity, including the SubclassOptionalData flags. Also, fix the
Instruction::clone implementations to preserve the SubclassOptionalData
flags. Finally, teach several optimizations how to handle
SubclassOptionalData correctly, given these changes.

This fixes the counterintuitive behavior of isIdenticalTo not comparing
the full value, and clone not returning an identical clone, as well as
some subtle bugs that could be caused by these.

Thanks to Nick Lewycky for reporting this, and for an initial patch!

2a610c7387 Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well. 
This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!)

12bb766ae9 Fix for PR3016: detect the tricky case, where there are 
unfoldable references to a PHI node in the block being folded, and disable
the transformation in that case.  The correct transformation of such PHI
nodes depends on whether BB dominates Succ, and dominance is expensive 
to compute here.  (Alternatively, it's possible to check whether any 
uses are live, but that's also essentially a dominance calculation. 
Another alternative is to use reg2mem, but it probably isn't a good idea to
use that in simplifycfg.)

Also, remove some incorrect code from CanPropagatePredecessorsForPHIs 
which is made unnecessary with this patch: it didn't consider the case 
where a PHI node in BB has multiple uses.

7f93dc8345 Switch obvious clients to Twine instead of utostr (when they were already using 
a Twine, e.g., for names).
 - I am a little ambivalent about this; we don't want the string conversion of
   utostr, but using overload '+' mixed with string and integer arguments is
   sketchy. On the other hand, this particular usage is something of an idiom.
