Get rid of the difference between file paths and directory paths. The Path class now simply stores a path that can refer to either a file or a directory. This required various changes in the implementation and interface of the class with the corresponding impact to its users. Doxygen comments were also updated to reflect these changes. Interface changes are: appendDirectory -> appendComponent appendFile -> appendComponent elideDirectory -> eraseComponent elideFile -> eraseComponent elideSuffix -> eraseSuffix renameFile -> rename setDirectory -> set setFile -> set Changes pass Dejagnu and llvm-test/SingleSource tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22349 91177308-0d34-0410-b5e6-96231b3b80d8
