Add a bool flag to StackObjects telling whether they reference spill
slots.  The AsmPrinter will use this information to determine whether to
print a spill/reload comment.

Remove default argument values.  It's too easy to pass a wrong argument
value when multiple arguments have default values.  Make everything
explicit to trap bugs early.

Update all targets to adhere to the new interfaces..

Refine the VTT entries for virtual bases to refer to the complete
object's vtable instead of constructor vtables.

Refine the AddressPoint calculations for VTT entries for virtual bases.

Make FixedStackPseudoSourceValue a first-class PseudoSourceValue by
making it visible to clients and adding LLVM-style cast capability.
This will be used by AsmPrinter to determine when to emit spill comments
for an instruction.

Add AsmPrinter comment flags to machine instructions so that AsmPrinter
can emit extra information in comments.

Add comment flags so AsmPrinter can output additional information when
emitting comments.  These flags carry semantic information not otherwise
easily derivable from the IR text.

non-type template parameters or constants of pointer-to-member

they are not dependent.

not treated as a pointer to member.

  - Comparing template parameter lists to determine if we have a redeclaration
  - Comparing template parameter lists to determine if we have equivalent
    template template parameters
  - Comparing template parameter lists to determine whether a template 
    template argument is valid for a given template template parameter.

Previously, we did not distinguish between the last two cases, which
got us into trouble when we were looking for exact type matches
between the types of non-type template parameters that were dependent
types. Now we do, so we properly delay checking of template template
arguments until instantiation time.

Also, fix an accidental fall-through in a case statement that was
causing crashes.

running IPSCCP early, and we run functionattrs interlaced with the inliner,
we often (particularly for small or noop functions) completely propagate
all of the information about a call to its call site in IPSSCP (making a call
dead) and functionattrs is smart enough to realize that the function is
readonly (because it is interlaced with inliner).

To improve compile time and make the inliner threshold more accurate, realize
that we don't have to inline dead readonly function calls.  Instead, just 
delete the call.  This happens all the time for C++ codes, here are some
counters from opt/llvm-ld counting the number of times calls were deleted vs
inlined on various apps:

Tramp3d opt:
  5033 inline                - Number of call sites deleted, not inlined
 24596 inline                - Number of functions inlined
llvm-ld:
  667 inline           - Number of functions deleted because all callers found
  699 inline           - Number of functions inlined

483.xalancbmk opt:
  8096 inline                - Number of call sites deleted, not inlined
 62528 inline                - Number of functions inlined
llvm-ld:
   217 inline           - Number of allocas merged together
  2158 inline           - Number of functions inlined

471.omnetpp:
  331 inline                - Number of call sites deleted, not inlined
 8981 inline                - Number of functions inlined
llvm-ld:
  171 inline           - Number of functions deleted because all callers found
  629 inline           - Number of functions inlined


Deleting a call is much faster than inlining it, and is insensitive to the
size of the callee. :)

  cannot be folded into target cmp instruction.
- Avoid a phase ordering issue where early cmp optimization would prevent the
  later count-to-zero optimization.
- Add missing checks which could cause LSR to reuse stride that does not have
  users.
- Fix a bug in count-to-zero optimization code which failed to find the pre-inc
  iv's phi node.
- Remove, tighten, loosen some incorrect checks disable valid transformations.
- Quite a bit of code clean up.
