	- Workaround for ocamlopt producing outputs adjacent to its source inputs, by having the tests copy the inputs into temporary directories in the output paths before building. - Patch by edward-san. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189081 91177308-0d34-0410-b5e6-96231b3b80d8
