John McCall 2de87f67e5 Reorganize the emission of (unfoldable) constant casts a bit, and
make sure that upcasts of member pointer types are covered as constants.
Fixed rdar://problem/9130221

John McCall 7a9aac2d9f Abstract out everything having to do with member pointers into the ABI
class;  they should just be completely opaque throughout IR gen now,
although I haven't really audited that.

Fix a bug apparently inherited from gcc-4.2 where we failed to null-check
member data pointers when performing derived-to-base or base-to-derived
conversions on them.

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 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.

Douglas Gregor aee1f51485 If we're generating code to create a pointer-to-member function
aggregate and the result of the aggregate is unused, bail out
early. Fixes PR7027.

Anders Carlsson 3572d44190 When computing the address of a virtual member function pointer, use the pointer width instead of hardcoding for 64-bit.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Daniel Dunbar 568e302a7f Fix some tests in -Asserts mode.
- FileCheck is a *huuuuge* improvement here.

 - Still feels like we could use a better tool for this though, either teach
   llvm-dis to spit out the FileCheck syntax, or provide another tool to turn a
   .ll into a "matchable" input.

 - Also on my Christmas list is better FileCheck diagnostics with missing
   variables or mismatches.
