Adding Cortex-A73 as an available target.

[SjoerdMeijer]

Summary

This adds support for Cortex-A73 as an available target.

Clang support is under review in "D20864: Adding support for Cortex-A73"

[rengolin]

Please, also add it to AArch64TargetParser.def.

Also, be aware that D20762 will probably change the target descriptions a bit.

[SjoerdMeijer]

Also added Cortex-A73 to AArch64TargetParser.def

[t.p.northover]

I assume AArch64 support is separated off rather than forgotten?

[t.p.northover]

Sorry, ignore that. I misread the diff (I was expecting more lines like in ARM.td).

1415

are you expecting attribute 22?

[SjoerdMeijer]

Thanks Renato, I have added the check for build attribute 22 that somehow got lost.

[rengolin]

LGTM, Thanks!

[SjoerdMeijer]

Sorry for asking, but would you mind looking at the Clang part in D20864 as well? Thanks.
