Nick Desaulniers 0f0727d971 drm/amd/display: readd -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines ... arch/x86/Makefile disables SSE and SSE2 for the whole kernel. The AMDGPU drivers modified in this patch re-enable SSE but not SSE2. Turn on SSE2 to support emitting double precision floating point instructions rather than calls to non-existent (usually available from gcc_s or compiler_rt) floating point helper routines for Clang. This was originally landed in: commit 1011745073 ("drm/amd/display: add -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines") but reverted in: commit 193392ed9f ("Revert "drm/amd/display: add -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines"") due to bugreports from GCC builds. Add guards to only do so for Clang.
