Summary:

extension:

  sve2, sve2-aes, sve2-sm4, sve2-sha3, bitperm

For existing CPUs these features are declared as unsupported to prevent
scheduler errors.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

David Spickett e01718cd60 [ARM, AArch64] Move ARM/AArch64 target parsers into
separate files to enable future changes.
    
This moves ARM and AArch64 target parsing into their
own files. They are still accessible through 
TargetParser.h as before.

Several functions in AArch64 which were just forwarders to ARM
have been removed. All except AArch64::getFPUName were unused,
and that was only used in a test. Which itself was overlapping
one in ARM, so it has also been removed.
