is morphed by AnalyzeNewNode into a previously
processed node, and different result values of
that node are remapped to values with different
nodes, then we could end up using wrong values
here [we were assuming that all results remap
to values with the same underlying node].  This
seems theoretically possible, but I don't have
a testcase.  The meat of the patch is in the
changes to AnalyzeNewNode/AnalyzeNewValue and
ReplaceNodeWith.  While there, I changed names
like RemapNode to RemapValue, since it really
remaps values.  To tell the truth, I would be
much happier if we were only remapping nodes
(it would simplify a bunch of logic, and allow
for some cute speedups) but I haven't yet worked
out how to do that.

va_list, not the value.  Patch fixes an assert on 
x86-64 and a wrong-code bug on x86.  I'm not completely sure, 
but I think it's a regression from r58306.

Does anyone run regression tests regularly on x86-64? The crash should 
have been picked up there.

The attached patch adds additional checks to -warn-objc-missing-dealloc. It checks that all ivars which are used in implementation of synthesized properties are either

a) released in dealloc if the property has retain" or "copy" attribute OR
b) not released in dealloc if the property has "assign" attribute

BindDecl better describes what the function does:

ImplicitConversionSequence and, when doing so, following the specific
rules of [over.best.ics]. 

The computation of the implicit conversion sequences implements C++
[over.ics.ref], but we do not (yet) have ranking for implicit
conversion sequences that use reference binding.

of copy initialization. Other pieces of the puzzle:

  - Try/Perform-ImplicitConversion now handles implicit conversions
    that don't involve references.
  - Try/Perform-CopyInitialization uses
    CheckSingleAssignmentConstraints for C. PerformCopyInitialization
    is now used for all argument passing and returning values from a
    function.
  - Diagnose errors with declaring references and const values without
    an initializer. (Uses a new Action callback, ActOnUninitializedDecl).
  
We do not yet have implicit conversion sequences for reference
binding, which means that we don't have any overloading support for
reference parameters yet.

With this commit, stuff like this is very close to working...

    [foo barf:^(int){ printf("whatever\n"); }];

Here is what is currently translates to...

    ((id (*)(id, SEL, void (^)(int)))(void *)objc_msgSend)((id)foo, sel_registerName("barf:"), (void (*)(int))__main_block_func_0);

I just need make sure the funky cast on objc_msgSend() is converted from "void (^)(int)" to "void (*)(int)". Since the cast doesn't appear in the source code, it needs to be converted in RewriteObjC::SynthMessageExpr().

Since the ARM constant pool handling supercedes the standard LLVM constant
pool entirely, the JIT emitter does not allocate space for the constants,
nor initialize the memory. The constant pool is considered part of the 
instruction stream.

Likewise, when resolving relocations into the constant pool, a hook into
the target back end is used to resolve from the constant ID# to the
address where the constant is stored.

For now, the support in the ARM emitter is limited to 32-bit integer. Future
patches will expand this to the full range of constants necessary.
