as part of a compilation. This is intended for two purposes: 1) Writing self-contained test cases for modules: we can now write a single source file test that builds some number of module files on the side and imports them. 2) Debugging / test case reduction. A single-source testcase is much more amenable to reduction, compared to a VFS tarball or .pcm files. llvm-svn: 305101
