Presumably this'll be split out into separate reviews for the components here? (I'd guess llvm-mc then clang integrated assembler, with readobj and yaml2obj in any order/don't have dependencies, unless they're needed for testing, in which case I guess they come first?)

I hesitate to comment on the specifics while it's all together as I imagine it'll become hard to follow the different commentary across the larger patch/different project areas, etc.

(though the flag design seems strange to me - having --crel and --experimental-crel, rather than having only the latter (and renaming it in the future, rather than using two flags now and removing one in the future))
