xen: fix gcov compilation
Currently enabling gcov in hypervisor won't build because although
26c9d03d ("gcov: Adding support for coverage information") claimed that
%.init.o files were excluded from applying compilation options, it was
in fact not true.
Fix that by filtering out the options correctly. Because the dependency
of stub.o in x86 EFI build can't be eliminated easily and we prefer a
generalised method going forward, we introduce nogcov-y to explicitly
mark objects that don't need to build with gcov support.

It is possible, when normalising a PV pagetable that the table has been freed
and reused for something else by the guest.
In such a case, data read might no longer be a pagetable, and fail the
truncation check. However, this should only be fatal if we encounter such a
page in the paused phase.
This check is now consistent with all other checks in the same area.
