d2e6a45722 When qualified lookup into the current instantiation fails (because it 
finds nothing), and the current instantiation has dependent base
classes, treat the qualified lookup as if it referred to an unknown
specialization. Fixes PR6031.

09bbc651f4 Switch the remaining code completions over to LookupVisibleDecls, 
after adding the ability to determine whether our lookup is a
base-class lookup. Eliminate CollectMemberLookupResults, since it is
no longer used (yay).

035ead209f Made ObjC method name mangling match GCC (which does it in a stupid and broken way that can give conflicts on method names containing underscores, but is needed for gdb to work because gdb does not know how to read ObjC class tables and relies on the mangling).

29ce3a3114 Avoid snowballing errors into additional warnings. To do better, we'd 
need an error term for the CFG.  I suspect we'll always have to cope
with getCFG returning 0, though, I'd love to see even that possibility
removed.

c580c5205f Switch code-completion for ordinary names over to the new(ish) 
LookupVisibleDecls, unifying the name lookup mechanisms used by code
completion and typo correction. Aside from the software-engineering
improvements, this makes code-completion see through using directives
and see ivars when performing unqualified name lookup in an
Objective-C instance method.

bff090648b Don't fold insufficiently aligned ldr/str into ldm/stm instructions. 
An unaligned ldr causes a trap, and is then emulated by the kernel with
awesome performance. The darwin kernel does not emulate unaligned ldm/stm
Thumb2 instructions, so don't generate them.

This fixes the miscompilation of Multisource/Applications/JM/lencod for Thumb2.

Generating unaligned ldr/str pairs from a 16-bit aligned memcpy is probably
also a bad idea, but that is beyond the scope of this patch.

52ce62f069 Improve the sorting of code-completion results. We now always sort by 
the "typed" text, first, then take into account
nested-name-specifiers, name hiding, etc. This means that the

ad7a5b07a7 When the visitSub method was split into visitSub and visitFSub, this xform was 
added to the FSub version. However, the original version of this xform guarded
against doing this for floating point (!Op0->getType()->isFPOrFPVector()).

This is causing LLVM to perform incorrect xforms for code like:

void func(double *rhi, double *rlo, double xh, double xl, double yh, double yl){
  double mh, ml;
  double c = 134217729.0;
  double up, u1, u2, vp, v1, v2;
        
  up = xh*c;
  u1 = (xh - up) + up;
  u2 = xh - u1;
        
  vp = yh*c;
  v1 = (yh - vp) + vp;
  v2 = yh - v1;
        
  mh = xh*yh;
  ml = (((u1*v1 - mh) + (u1*v2)) + (u2*v1)) + (u2*v2);
  ml += xh*yl + xl*yh;
        
  *rhi = mh + ml;
  *rlo = (mh - (*rhi)) + ml;
}

The last line was optimized away, but rl is intended to be the difference
between the infinitely precise result of mh + ml and after it has been rounded
to double precision.

e8c8cd2a58 Don't report ambiguities in the user-defined conversion if we weren't supposed 
to be considering user-defined conversions in the first place.

Doug, please review;  I'm not sure what we should be doing if we see a real
ambiguity in selecting a copy constructor when otherwise suppressing
user-defined conversions.
