Building with ThinLTO requires that we use llvm-lib.exe as $(AR) because Microsoft's lib.exe doesn't understand the file format.
Without LTO, it's entirely possible to mix and match LLVM and MS's programs, but for simplicity let's just say we'll always use lld-link and llvm-lib together.
As a bonus, we can use -llvmlibthin to generate thin libraries, which store pointers to the original obj files rather than copy the data. As long as we don't need to ship or share the libs (which we don't) this can save us some work.
