We can't do this during the target hook ix86_set_current_function since at that
time (WPA phase) the cfun is NULL, even if we want to update the target option
node for to->decl, but the passed down fndecl is NULL.
I made a patch to rebuild the target option node for to->decl DECL once
reload_optimization_node is true. For this failure case, the
opts.x_flag_unsafe_math_optimizations has changed, we have to sync it to
x_ix86_unsafe_math_optimizations and rebuild.
