Hello All!
This series adds all the armv8a cores currently known to any released
version of gcc.
First, we do a bit of cleanups in the existing menu: re-order the cores,
simplify hiding non-64-bit cores, rename armv8 to armv8a.
Second, as all armv8a cores are guaranteed by the ISA to have a VFPv4,
we disallow building a soft-float toolchain on those cores when in
64-bit mode.
Now we add a bunch of armv8a cores, cortex and non-cortex alike, with a
few armv8.1a variants as well.
It is to be noted that we do have at least one armv8a core that is in
fact 32-bit only, while we also do have a few armv8a cores that are
64-bit only (or at least gcc does not recognises them in arm mode).
Eventually, we add a build-only test for all those toolchains, to check
that at least the toolchains do build. This final commit is not meant to
be applied, it adds way too many tests.
This series relies on the previous architecture series I've recently
sent:

PS. I've sent this series as a real pull-request, just to see how
the new patchwork handles it: currently, series are sorted by the
first patch, and patchwork misses the cover-letter. Let's see if
a cover-letter that is a pull-request gets noticed.
