Since I’m working on the stdlib, the corruption often shows up in there, so —clean is needlessly heavy-handed. I don’t need to rebuild clang or llvm, and I probably don’t need to rebuild swiftc. Is there any way to do this?

The build directory has separate subdirectories for the build products of llvm and clang and swift. Deleting the swift directory will safely preserve llvm and clang, but not swiftc.
