clang: error: unable to make temporary file: /etc/cc: can't make
unique filenamePermission denied

Also, audited the uses of MakeErrMsg to make the prefix strings
consistent (not end with newline/punctuation/space/": ").

the symlink. This lets clang find its headers when invoked through
a symlink. rdar://6602012

This method allows one to create a directory, and optionally create all parent
directories that do not exist.
The original implementation would require that *all* directories along a path
are writable by the user, including directories that already exist. For example,
suppose we wanted to create the directory "/tmp/foo/bar", and the directory
"/tmp" already exists, but not "/tmp/foo". Since "/tmp" is writable by all
users, the original implementation would work, and create "/tmp/foo", followed
by "/tmp/bar".
A problem occurred, however if one wanted to created the directory
"/Users/myuser/bar" (or equivalently "/home/myuser/bar"), and "/Users/myuser"
already existed and is writable by the current user. The directory
"/User/myuser" is writable by the user, but "/User" is not. The original
implementation of createDirectoryOnDisk would return with failure since "/User"
is not writable, even though "/User/mysuser" is writable.
The new implementation works by recursively creating parents as needed, and thus
doesn't need to check the permissions on every directory in a path.

Make the sys::Path::getFileStatus function more efficient by having it
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.

* Add a method: bool isAbsolute() const, which determines if the path name
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.

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.

1. Use isValid() to check validity of the resulting path name in the
eraseSuffix even though we can't think of a case where eraseSuffix could
possibly cause an invalid path name.
2. Rewrite isValid() to not use the deprecated realpath function any more.
It now just uses isascii to make sure all the characters are legit.
