The tune-x86_64.inc file is conceptually flawed. x86_64 is more akin to
the x86 and x86-32 ABIs defined in arch-x86.inc than it is a concrete
tune file, such as i586 or core2 - to the extent that everything but the
default tune is defined in the arch-x86.inc file. This becomes very
apparant when attempting to include tune-x86_64.inc in the x86 tune
hierarchy.
Remove the tune-x86_64.inc tune file in favor of it being an ABI
definition in arch-x86.inc and relying on the linear hierarchy of
concrete cpu-types in tune-i586, tune-core2, and tune-corei7.
core2_64 should suffice in lieu of x86_64 for all but a couple esoteric
corner cases involving older pre-core2 CPUs. In these cases, if they
exist at all, the BSP can replace the include tune-x86_64.inc with
arch-x86.inc and set the default tune to x86_64.

Core2 has both a 32b and a 64b variant. Currently, core2 implies 32b,
while core2_64 is the 64b version. This implicit 32b mode will become
confusing in later architectures, such as corei7, where it would be
natural for people to assume "corei7" meant 64 bit.
Rather than carrying forward an implicit 32b mode and rather than
changing the naming scheme part way through the architecture hiearchy,
make the 32b and 64b variant explicit in the tune name by changing core2
to core2-32. This patch also standardises on using '-' in the names.

-march specifies which ISA to use. -mtune specifies which cpu-type to
optimize instruction ordering for, but not which ISA to use. There are
times when it may make sense to specify mtune=generic and use a more
specific march, such as core2, but the opposite makes little sense at
all: use cpu-type specific ISA, but order the instructions
generically. While the -mtune is implied by -march, gcc does not verify
it is using -mtune=core2 with:
gcc -Q -march=core2 --help=target
Explicitly specify -mtune=core2 to be sure.
Add a comment header describing the CPUs targeted by this tune file.

I commented out two blocks of code that are responsible
for getting the book's title to format onto the title page.
Commenting the code out suppresses the title from the
PDF version's title page yet retains the title text for the
HTML tab space of the browser. The reason this is necessary
is because the BitBake User Manual uses an image file for
the title. Thus, it is not necessary to print the title
again.

There were two section tags that used the same id name "classes".
One was in the intro chapter and one was in the metadata chapter.
This was causing an exception in the PDF creation process and
breaking it. I renamed the tag in the metadata chapter
"metadata-classes".

This file was evidently a "working" file and not included in the
manual at the point Bill left off. The wmat branch, however, had
a load of commits dedicated to this file. Rather than attempt to
replay them all one-by-one, I simply copied the file from the
wmat branch and hand-inserted the changes to make it equal to what
was there. Note also that I re-formatted the file to have the
same formatting standards I use in the YP manuals.
