Subject: [PATCH 5.4 01/43] gcc-plugins: Rename last_stmt() for GCC 14+

5.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kees Cook <keescook@...omium.org>

commit 2e3f65ccfe6b0778b261ad69c9603ae85f210334 upstream.

In GCC 14, last_stmt() was renamed to last_nondebug_stmt(). Add a helper
macro to handle the renaming.
