* Remove unneeded header files.
* Move RedirectFD static function to lib/System/Unix/Program.cpp
* Delete RunProgramWithTimeout, now implemented by
  sys::Program::ExecuteAndWait. RunProgramWithTimeout is now a convenience func.

* Make the OutputC and OutputAsm functions work with sys::Path for the output
  file name instead of using std::string.
* Get rid of extraneous "toString" calls.
* Change "removeFile" to sys::Path::destroyFile()

llvm-svn: 19000

* Remove the "removeFile" function, now implemented by the
  sys::Path::destroyFile method.
* Make the FileRemove work with a sys::Path instead of a std::string

createTemporaryFile semantics where it doesn't create a fully unique name
if the basename doesn't exist. This functionality is now optionally
provided by the boolean reuse_current parameter to createTemporaryFile and
makeUnique. The default values differ because of the way these functions
are used in LLVM.

* Convert getUniqueFilename -> sys::Pat::makeUnique()

llvm-svn: 18948

* Fix implementation and documentation about LLVMGCCDIR/bytecode-libs
* Add the makeUnique method, replacement for getUniqueFilename in Support.
* Add the sys::CopyFile function, replacement for CopyFile in Support.
* Move GetLLVMConfigDir() into generic code area since its generic.

llvm-svn: 18947

Remove getUniqueFilename and CopyFile. These are now implemented by
sys::Path::makeUnique and sys::CopyFile, respectively.
