testsuite: fixup tbaa test again
Test was broken until r15-4684-g2d1d6be00257c5 which made it actually
run and r15-4685-g091e45b4e97d1e which applied fixes other than the
trivial rename.

But more is needed: this gets the test working properly in terms of scanning
the dump and handling the interaction w/ LTO with not producing an executable
(did try ltrans scan but that didn't work either).

Unfortunately, the test seems to fail for me on godbolt even going back to
GCC 7.1 or thereabouts, hence XFAIL. However, if I revert r9-3870-g2a98b4bfc3d952,
I do get an ICE in fld_incomplete_type_of -- because we do far more checking
with LTO now on (in)complete types. And reverting it on releases/gcc-9 actually
makes it give 0.

In summary: fix the test fully so it really does run and we get a check
for ICEing at least, and mark the dg-final scan as XFAIL so Honza can
comment on that.

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
