Subject: [PATCH] gcc-plugins: Fix build for upcoming GCC release

From: Palmer Dabbelt <palmer@...osinc.com>

The upcoming GCC release has refactored the gimple plugin interface a
bit and unless gimple-iterator.h is included before gimple-fold.h I end
up with a bunch of missing declarations when building the stack
protector plugin.
