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.

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.

Failure to do this breaks relative paths which begin with '..'.
This issue was caught by the (still nascent) coverage bot.

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.
