Richard Smith dd5bdd8de7 Remove constant member pointer support from Expr-based constant emission now
that APValue-based constant emission knows how to emit member pointers.

Richard Smith dafff94759 constexpr irgen: Add irgen support for APValue::Struct, APValue::Union,
APValue::Array and APValue::MemberPointer. All APValue values can now be emitted
as constants.

Add new CGCXXABI entry point for emitting an APValue MemberPointer. The other
entrypoints dealing with constant member pointers are no longer necessary and
will be removed in a later change.

Switch codegen from using EvaluateAsRValue/EvaluateAsLValue to
VarDecl::evaluateValue. This performs caching and deals with the nasty cases in
C++11 where a non-const object's initializer can refer indirectly to
previously-initialized fields within the same object.

Building the intermediate APValue object incurs a measurable performance hit on
pathological testcases with huge initializer lists, so we continue to build IR
directly from the Expr nodes for array and record types outside of C++11.

Chris Lattner 0e62c1cc0b remove unneeded llvm:: namespace qualifiers on some core types now that LLVM.h imports
them into the clang namespace.

John McCall 2979fe01da After some discussion with Doug, we decided that it made a lot more sense
for __unknown_anytype resolution to destructively modify the AST.  So that's
what it does now, which significantly simplifies some of the implementation.
Normal member calls work pretty cleanly now, and I added support for
propagating unknown-ness through &.

John McCall a738c25f5e Use the "undergoes default argument promotion" bit on parameters to
simplify the logic of initializing function parameters so that we don't need
both a variable declaration and a type in FunctionArgList.  This also means
that we need to propagate the CGFunctionInfo down in a lot of places rather
than recalculating it from the FAL.  There's more we can do to eliminate
redundancy here, and I've left FIXMEs behind to do it.

John McCall f3a8860ee1 More capturing of 'this': implicit member expressions. Getting that
right for anonymous struct/union members led to me discovering some
seemingly broken code in that area of Sema, which I fixed, partly by  
changing the representation of member pointer constants so that    
IndirectFieldDecls aren't expanded.  This led to assorted cleanups with   
member pointers in CodeGen, and while I was doing that I saw some random
other things to clean up.

John McCall 284c48fff6 Do a proper recursive lookup when deciding whether a class's usual
deallocation function has a two-argument form.  Store the result of this
check in new[] and delete[] nodes.
