Fix CodeGen/AMDGPU/fcanonicalize-elimination.ll on FreeBSD 11.0

[arichardson]

Summary

On FreeBSD11.0 the FileCheck NOT string "1.0" will be matched by
.amd_amdgpu_isa "amdgcn-unknown-freebsd11.0--gfx802" at the end of the
file. Add a CHECK for that directive to avoid failing the test.

I will remove the extra "prints" before committing

We should probably just fix by using explicit triples in the run lines. We should also probably just unset the default OS if it's ever used
