Chris Packham 7c4055601a gcc-plugins: arm_ssp_per_task_plugin: Fix for older GCC < 6
commit 259799ea5a upstream.

Use gen_rtx_set instead of gen_rtx_SET. The former is a wrapper macro
that handles the difference between GCC versions implementing
the latter.

This fixes the following error on my system with g++ 5.4.0 as the host
compiler

   HOSTCXX -fPIC scripts/gcc-plugins/arm_ssp_per_task_plugin.o
