Add driver support for Qualcomm Kryo cpu.

[mcrosier]

Summary

Add support for Kryo.

[mcrosier]

Format the tests to match those already in tree.

Don't add support for zcz and zcm just yet; this needs additional testing.

[rengolin]

I'm assuming you also have the LLVM counterpart?

[t.p.northover]

Looks reasonable to me.

Tim.

Yes, but I haven't made them public just yet.

It would have been better to commit the LLVM parts first. Now, there will be a range where kyro will be accepted by Clang but broken when it gets to setup the target.
