  Changed paths:

    M libcxx/utils/libcxx/test/newformat.py

  Log Message:
  -----------
  [libc++] Make sure tests are run in a unique directory

This will allow simplifying executors by always just copying the whole
%T, and assuming that all file dependencies are contained in it.

Superseeds https://reviews.llvm.org/D78245, which tried to make %T unique
in Lit, but which encountered push back.
