XRay support flag in TargetOptions

Browse Source 
Specify where XRay is supported. I only test ARM64 and x86_64, but hey
those others should work too, right? LLVM documentation says that MIPS
and PPC are also supported, but I don't have the hardware, so I won't
pretend. Naturally, more targets can be added later with more testing.
