After disabling tsan for x86_64, the builds finally went OK, and all tests succeeded.  So these tarballs now also have compiler-rt in them, though unfortunately still no libc++:

SHA256 (clang+llvm-3.8.0-rc2-amd64-unknown-freebsd10.tar.xz) = d6a709e38aa274cc58130b755ef3c1c1fc34b36cc2bfcb6bfa4118b23b0c834e
SHA256 (clang+llvm-3.8.0-rc2-i386-unknown-freebsd10.tar.xz) = 840b3a391ef3dfec20ed5464230caad91f6431e655d0c6ae06cbabdd7ed12a73
