I'd assume this would be handled like the LLVM sanitizer runtimes builds. Though I'm wondering if that would cause problems. The GPU builds are all LTO for both performance and ABI stability.

@petrhosek any idea if it's reasonable to have a flag that pushes LLVM-IR for the whole runtimes build? Only problem I can imagine is compiler-rt libcalls, but even in those cases I think the current toolchain will link everything.
