This patch adds the new ISA data structures.  The idea is to use an
sbitmap for carrying these around internally.  We don't make much use
of this yet, but will increasingly migrate over to this in the
following patches.  All cores and architectures currently have both
old and new encodings for now.

For simplicity and clarity we introduce internally the concept of
ARMv7ve.  It doesn't change any visible behaviour.

There's also a bit of tidying up of the various supported cores,
sorting them by profile.

* arm-isa.h: New file.
* arm-protos.h: Include it.
* arm-arches.def: Add new ISA field to all entries.  Drop bogus
armv8.1-a+crc architecture.
* arm-cores.def: Similarly.  Group ARMv8 cores by profile.
* arm-opts.h (enum processor_type): Adjust for new field.
* arm.c (struct processors): New field 'isa_bits'.
(all_cores, all_architectures): Initialize new field.
* arm-tables.opt: Regenerated.
* arm-tune.md: Regenerated.
