e209be4985 Stub out a Path::GetMainExecutable call to find the path to the
main executable of a program.  This needs to be implemented on windows.

c7f485fd71 Use the stat information in the Path object, if it is already obtained. This
avoids a call to ::fstat by MappedFile when the file size information was
already obtained by the Path object.

200c6f9c3d For PR789:

return a pointer to the FileStatus structure rather than copy it. Adjust
uses of the function accordingly. Also, fix some memory issues in sys::Path.

d394617a55 Add a uniqueID field to the FileStatus structure for Paths. This will map
to the inode number on Unix and something far less unique on Windows. The

  is absolute or not.
* Implement caching of file status information in the Path object. Allow it
  to be updated forcefully or lazily re-fetched from the cached value.

448e2460e0 Make the removal of files use Path::eraseFromDisk just like it does for
the removal of directories. Using std::remove is indiscriminate and can
lead to the removal of things like /dev/null if run as root. The
Path::eraseFromDisk method ensures that we only ever remove regular files
or directories, but never character or block special nodes.  This should
clear up the problem with usage like: llvm-as -o /dev/null which is used
in the llvm-test makefiles.

4857253d98 Change Path::getStatusInfo to return a boolean and error string on an error
instead of throwing an exception.  This reduces the amount of code that is
exposed to exceptions (e.g. FileUtilities), though it is clearly only one step
along the way.

9c6c94a806 simple optimization: don't bother calling "exists" (which calls the syscall
"access").  Instead, just let the open call fail if the file doesn't exist.
This reduces the # syscalls executed.
