Don't mix and match between the just-built clang and the host clang when ASAN is enabled. rdar://problem/45273748

@compnerd I got back to this and managed to reproduce the failure locally with an Ubuntu 16.04 docker image and you were right, the check was the wrong way around. The changes as they stand now fixed the ASAN mismatch in Was there a specific requirement for 3.9+ building libdispatch here or was this just a known good configuration? It seems to build fine when I drop it to > 3.7 locally (my Ubuntu 16.04 docker setup has 3.8). |
