[PATCH] Add nominal support for 'shave' target.

[Chandler Carruth]

I agree with Joerg about submitting the separate cleanup change separately (feel free to just pull it out and commit it).

More detailed comments below.

I'm not a huge fan of the "Movi" prefix. Maybe just "Movidius" or "SHAVE"? If this is only used for the shave-* triples, I'd probably go with SHAVE.

I would also suffix it with ToolChain or something. It's not about Clang, its about the toolchain. (The use of 'GCC' here is because GCC actually ships a complete toolchain)

I suspect these should be named MoviCompile and MoviAsm. I would also probably call these "Compiler" and "Assembler" because I'm a bit of a pedant. ;]

Similar to the above, I'd probably call this SHAVE given that some of the ones above are XCore.
