* targhooks.c (default_hidden_stack_protect_fail): Fall back to
default_external_stack_protect_fail if visibility is not supported
or not flag_pic.
* config/i386/i386.c (ix86_stack_protect_fail): New function.
(TARGET_STACK_PROTECT_FAIL): Define.
* config/i386/i386.md (stack_protect_si): Change CLOBBER into
SET to zero.
(stack_protect_di): Likewise. Use %k2 instead of %2 to avoid
invalid instruction xorl %rax, %rax.
