[Driver][SYCL] Enable generation of spv based fat objects #4608
Conversation
When generating fat objects with -fsycl, our default behavior is to generate and store the LLVM-IR for the device side compilation. Update the behavior, introducing -fsycl-device-obj=arg (where arg is spirv or llvmir) to create the desired 'object' contents. This is a precursor to the enabling the ability to consume these spv based objects (or llvm-ir) seamlessly.

Moved to draft. Exposing the functionality of creating the fat objects with SPIR-V should only occur once we can properly consume both LLVM-IR and SPIR-V type fat objects seamlessly. |

@AGindinson, can you take a look? This is part of the larger SPIR-V to LLVM-IR change. |

Mostly LGTM. Do I understand correctly that #5251 should go in first?
