Changes in v7:
1. Remove stack_protect_guard_decl and pushing_stack_protect_guard_decl.
2. Declare the internal stack protection guard with
lang_hooks.types.type_for_mode (ptr_mode, 1))
so that it can be initialized as an integer.
3. Add c-c++-common/pr90108-2.c to verify that c_stack_protect_guard_decl_p
works properly for LP64 targets.
This still has the special case code to allow redeclaration with a
different type, and I still don't see why that's a thing we want to allow.
I think we can drop the
duplicate_stack_protect_guard_decl_p/keep_oldtype code.
Then ssp-global-2.C will fail, but I think that's fine, people can write
unsigned (or size_t, or uintptr_t).
