Subject: [PATCH] [clang][docs] Remove extra backslashes in -ffinite-math-only
 help text

  Fix issue #156165: __FINITE_MATH_ONLY__ macro was rendered with
  unnecessary backslash escapes in ClangCommandLineReference.html.

  The double backslashes in the Options.td string were being emitted
  literally, producing e.g. \_\_FINITE\_MATH\_ONLY\_\_ in the generated docs.
