Rework the way virtual primary bases are added when laying out classes. Instead of doing it as a separate step, we now use the BaseSubobjectInfo and use it when laying out the bases. This fixes a bug where we would either not add a primary virtual base at all, or add it at the wrong offset.

Change RecordLayoutBuilder::LayoutNonVirtualBase to take a BaseSubobjectInfo. No functionality change.

llvm-svn: 105103

Move computing the base subobject info for a class into the RecordLayoutBuilder because we're going to need it to be able to correctly add offsets for primary virtual bases.

 - Docs are fairly sketchy, if someone wants to pore through gcc to look for
   holes I'd appreciate any failing test cases!

Fold the ASTRecordLayoutBuilder::ComputeLayout overload that takes an ObjCInterfaceDecl pointer into its only callsite.

llvm-svn: 104672

Move the relevant ASTContext member functions that deal with ASTRecordLayoutBuilder into RecordLayoutBuilder.cpp. This matches the way we interact with other builder classes (CGRecordLayoutBuilder, VTableBuilder and VTTBuilder) and it also allows for making ASTRecordLayoutBuilder a private class without a header file.

Add a SizeOfLargestEmptySubobject member to ASTRecordLayout. For C++ classes this will hold the largest empty subobject or 0 if the class doesn't have any empty subobjects.

Add raw_ostream operators to NamedDecl for convenience. Switch over all users of getNameAsString on a stream.

The next step is to print the name directly into the stream, avoiding a temporary std::string copy.

Split adding the primary virtual base offsets out into a separate pass. This fixes a bug where we would lay out virtual bases in the wrong order.
