mtklein 795423198b GN: Build and link with LLD when using our Clang toolchain.
I am hoping this makes it easier to get *SAN bots going.
Today we're generating a libcompiler_rt.a that's using a
relocation type that the ld on the bots doesn't know about.
This lld is will know about anything our Clang generates.
