Add support for Cortex-A17

[mwahab]

Summary

Adds support for the Cortex-A17 processor to Clang.

[mwahab]

Depends on the linked LLVM patch to add support in the ARM backend.

[rengolin]

If this defaults as v7, it'll have the right flags but behave like an A9 in the back-end, right? Is that expected, or should we add it to ARM.td and friends first?

The will depend on the LLVM patch which adds the Cortex-A17 to the backend and which will have to be committed first.

Ignore me, I only saw the other request now. :)
