John McCall c29eb8a9d1 Clean up a very silly use of first-class aggregates.

John McCall a1dee5300b Experiment with using first-class aggregates to represent member function 
pointers.  I find the resulting code to be substantially cleaner, and it
makes it very easy to use the same APIs for data member pointers (which I have
conscientiously avoided here), and it avoids a plethora of potential
inefficiencies due to excessive memory copying, but we'll have to see if it
actually works.

John McCall 131d97d809 Extract member function pointer comparison and null comparison into 
the ABI code.  Implement correct semantics for these on ARM.

I believe this completes the implementation of member function pointers
on ARM.

I think I'm going to switch member function pointers over to be
non-aggregates while I have all this in mind.

John McCall 1c456c89dc Abstract out member-pointer creation. I'm really unhappy about the current 
duplication between the constant and non-constant paths in all of this.

Implement ARM ABI semantics for member pointer constants and conversion.

John McCall 84fa510aa9 Abstract more member-pointerness out.

John McCall a8bbb82c55 Abstract out member-pointer conversions. 
Pretty much everything having to do with member pointers is ABI-specific.

John McCall d9c6c0b583 Implement the call parts of the member-function-pointer ARM C++ ABI.

John McCall 475999dcf9 Extract calls to method pointers out as an ABI routine. 
No functionality change.

John McCall 86353416a7 The ARM C++ ABI is sufficiently different from the Itanium C++ ABI that 
it deserves its own enumerator.  Obviously the implementations should
closely follow the Itanium ABI except in cases of divergence.

Charles Davis 53c59df2f7 Implement support for member pointers under the Microsoft C++ ABI in the 
AST library.

This also adds infrastructure for supporting multiple C++ ABIs in the AST.

Charles Davis 4e786ddccb IRgen: Add a stub class for generating ABI-specific C++ code. 
This class only supports name mangling (which is apparently used during C/ObjC
codegen). For now only the Itanium C++ ABI is supported. Patches to add a
second C++ ABI are forthcoming.
