[PATCH 0/5] Add support -mcpu=thunderxt88pass1 and needed changes to support that

[Andrew Pinski <apinski at cavium dot com>]

To Add support for -mcpu=thunderxt88pass1, I needed to fix up a few
things in the support for -mcpu=native.  First was I wanted to do the same
cleanup that was done for some of the other .def files and move the
#undef into the .def files instead of the .h files.
Second to make it easier to understand the implemention_id and part numbers
are really numbers, move them over to use integer to compare against
instead of strings which allows for easier comparisons later on.
Third fix the way we compare imp and part num; that is instead of finding
the part number and then comparing the imp, we find both numbers first
and then search for the ones that match.
Add a comment to the aarch64-cores.def file in front of each group of cores
to signify the groups of company's cores.
And all of this allows for adding variant for the check of the cores
which allows for thunderxt88pass1 to be added.

The reason why thunderxt88pass1 is seperate from thunderx is because
thunderx is changed to be an ARMv8.1 arch core while thunderxt88pass1
is still an ARMv8 arch core.

I tested each of these patches seperately.

Ok for the trunk even though I missed out on stage 1?

Thanks,
Andrew
