This patch seems to solve the problem

 TREE_TARGET_OPTION (target_option_default_node));
+  func_options.x_ix86_arch_string = ix86_arch_string;
+  func_options.x_ix86_tune_string = ix86_tune_string;

   new_target = ix86_valid_target_attribute_tree (args, func_options,
  global_options_set);


cl_target_option_restore does not touch ix86_arch_string and ix86_tune_string.
This has to be managed explicitly. I am testing this patch now.

Thanks,
Sri

Looks like a system_header check doesn't work anymore.

 Started with r203634.

I am able to reproduce the problem though I get the bogus warning:

test.cc:4:24: warning: macro __corei7__ is not used [-Wunused-macros]

I am triaging.
