The %T lit expansion expands to a common directory shared between all the tests in the same directory, which is unexpected and unintuitive, and more importantly, it's been a source of subtle race conditions and flaky tests. In https://reviews.llvm.org/D35396, it was agreed that it would be best to simply ban %T and only keep %t, which is unique to each test. When a test needs a temporary directory, it can just create one using mkdir %t.
This patch removes %T in clang.

The builder prints out the following IR:
\5CCoverageMapping\5COutput\5Ctest\5Cf1.c
The updated test in r276367 expects path separators to be either '/' or
'\\', so it chokes on the unexpected "5C" stuff. I'm not sure what that
is, but I included a kludge that should work around it.

We should be able to use `mkdir` without turning on `REQUIRES: shell`.
Moreover, this test should check for a path separator which precedes the
relative filename to make sure that absolute paths are being used.

This fixes the issue of having duplicate entries for the same file in a
coverage report s.t none of the entries actually displayed the correct
coverage information.
