Adrian Prantl 4b9cf31ba0 Add a callback to swift::reflection::MemoryReader that allows LLDB to provide ...

swift::reflection::TypeInfo for (Clang-)imported non-Objective-C types. This is
needed to reflect on the size mixed Swift / Clang types, when no type metadata
is available for the C types.

This is a necessary ingredient for the TypeRef-based Swift context in
LLDB. Because we do not have reflection metadata for pure C types in Swift,
reflection cannot compute TypeInfo for NominalTypeRefs for those types. By
providing this callback, LLDB can supply this information for DWARF, and
reflection can compute TypeInfos for mixed Swift/C types.
