[PATCH 6.16.y] gcc-plugins: Remove TODO_verify_il for GCC >= 16

[PATCH 6.16.y] gcc-plugins: Remove TODO_verify_il for GCC >= 16

[Brahmajit Das]

From: Kees Cook <kees@kernel.org>

[ Upstream commit a40282dd3c48 ]

GCC now runs TODO_verify_il automatically[1], so it is no longer exposed to
plugins. Only use the flag on GCC < 16.
