LowerTypeTests: Implement exporting of type identifiers.
Type identifiers are exported by: - Adding coarse-grained information about how to test the type identifier to the summary. - Creating symbols in the object file (aliases and absolute symbols) containing fine-grained information about the type identifier. Differential Revision: https://reviews.llvm.org/D28424 llvm-svn: 292462
