Subject: [PATCH] [leaks] Fix a leak recently introduced to the pragma
 handling. This whole code would be better with std::unique_ptr managing the
 lifetimes of the handlers, but I wanted to make a targeted fix to the leaks
 first. With this change, all of the Clang preprocessor tests are leak free
 with LSan.
