Subject: [PATCH 5.15.y 2/2] gcc-plugins: Reorganize gimple includes for GCC 13

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

mainline commit: e6a71160cc145e18ab45195abf89884112e02dfb

The gimple-iterator.h header must be included before gimple-fold.h
starting with GCC 13. Reorganize gimple headers to work for all GCC
versions.
