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.

BZ_OK (meaning more data is expected) but there is no more input data. In
this case, the input file is probably truncated. Generate an exception that
indicates this case when its detected.

handling zero length files a little more intelligently. If both files are
zero length then we return 0 (true) indicating a match. If only one of the
files is zero length then we return 1 (false) indicating that the files
differ. If the files don't agree in length then they can't match so we
skip the first loop that looks for a quick match.

cases it represented them as 'unsigned's, which are not enough for 64-bit
hosts. In other cases, it represented them as uint64_t's, which are
inefficient for 32-bit hosts.
This patch unifies all of the sizes to use size_t instead.

portability, the --track-space option was inadvertently ignored. This patch
fixes that so that sys::Process::GetMallocUsage() is only invoked if the
--track-spaces option is given. Apparently the mallinfo() call that
GetMallocUsage() uses is *very* slow, especially when processing very large
modules like projects/llvm-test/MultiSource/Applications/kimwitu++.

* Move system dependent implementation out of this file.
* Make implementation use sys::Process::GetMallocUsage where necessary.
* Make implementation use sys::Process::GetTimeUsage where necessary.

* Pass sys::Path instead of std::string for paths
* Correct the types of arguments passed to RunProgramWithTimeout due to its
interface using sys::Path instead of std::string
* Replace "/dev/null" (not portable) with empty string which
sys::Program::ExecuteAndWait recognizes as "redirect to bit bucket"

* 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()

sys::Path::destroyFile method.
* Make the FileRemove work with a sys::Path instead of a std::string

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

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

* Make FindExecutable a thin veneer over sys::Program::FindProgramByName.

Remove AllocateRWXMemory as it is not used any more in LLVM. The function
has been replaced with sys::Memory::AllocateRWX several months ago.

longer present in LLVM. They have been replaced with the sys::Path methods
makeReadable and makeExecutable, respectively.

The ReadFileIntoAddressSpace and UnmapFileFromAddressSpace functions are no
longer used by LLVM. Remove them. Replacement functionality for both
functions is now encapsulated in the sys::MappedFile class.

bzip2: block size 9 -> 5, reduces memory by 400Kbytes, doesn't affect speed
or compression ratio on all but the largest bytecode files (>1MB)
zip: level 9 -> 6, this speeds up compression time by ~30% but only
degrades the compressed size by a few bytes per megabyte. Those few
bytes aren't worth the effort.

verbatim without compression. Also, don't warn if there's no compression

function needs to be properly converted to lib/System and implemented via
read/write if there's no mmap of file support.
