a3c69aeb65 "UNIX paths can contain non-ASCII characters, so Path::isValid() should not reject paths with such characters in them. The attached patch removes the check from Path::isValid()."

3222b9be04 Make Unix.h:MakeErrMsg separate the prefix and errno string, so we get: 
clang: error: unable to make temporary file: /etc/cc: can't make
  unique filename: Permission denied

instead of 

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

for example.

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

3c50fdf4ca If an executable is run through a symlink, dladdr will return the 
symlink.  We really want the ultimate executable being run, not
the symlink.  This lets clang find its headers when invoked through
a symlink. rdar://6602012

1d0436cdb0 Re-implemented Path::createDirectoryOnDisk (for Unix). 
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.

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.
