Add 'shave' processor name to Triple

[chandlerc]

LGTM with minor tweak to wording.

You should also mention in the commit log when you submit this that the purpose initially is just to allow Clang to process these triples and redirect compilation to the Movidius dev kit.

I don't think this is really the SoC.

I would say: "SHAVE: Movidius Myriad 2 vector VLIW processors" as that's how http://www.movidius.com/our-technology/myriad-2-platform/ describes them.

     amdil64,    // AMDIL with 64-bit pointers
     hsail,      // AMD HSAIL
     hsail64,    // AMD HSAIL with 64-bit pointers
     spir,       // SPIR: standard portable IR for OpenCL 32-bit version
     spir64,     // SPIR: standard portable IR for OpenCL 64-bit version
     kalimba,    // Kalimba: generic kalimba
-    LastArchType = kalimba
+    shave,      // SHAVE: Movidius SoC
+    LastArchType = shave
