I think the unique_file() function was originally meant for just temp files, hence the 0600 permissions.   The other part of my patch is a function to flip on the 'x' bit on any file.

To clarify a bit here:

Yes, I believe that unique_file was originally meant for just temp files, unfortunately it's been pressed into service everywhere. The interface that you're working on would be excellent to replace all but the temp file usage throughout llvm so I'm fine with this going away at that point.
