b2db8e47e2 Constify the getClassName routine and variables that come out of it, 
and then use it for forward decl names.

75b90c4a86 Use the new forward declaration scheme for records. Also add more 
caching of results after we create them.

7ec12c928a Revert my patches which removed Diagnostic.h includes by moving some operator overloads out of line. 
This seems to negatively affect compile time onsome ObjC tests
(which use a lot of partial diagnostics I assume). I have to come
up with a way to keep them inline without including Diagnostic.h
everywhere. Now adding a new diagnostic requires a full rebuild
of e.g. the static analyzer which doesn't even use those diagnostics.

This reverts commit 6496bd10dc3a6d5e3266348f08b6e35f8184bc99.

c9e6924fb2 r149474 went a bit too far when combined with type caching. If we want 
a full type go ahead and emit it if we currently only have a forward
declaration.

Fixes gdb bots for gdb1090.exp and call-ar-st.exp.

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.

this class?"

expression. Also improve the documentation of Expr::Evaluate* to indicate which
of them will accept expressions with side-effects.
