A workaround in codeview debuginfo generation was to declare a condfail instruction as inlined to avoid using 0 as an artificial line location. However, this was done without accounting for scopes that were already legitimately inlined. So we'd end up with a condfail inlined from function B into function A and then the IRGen for the condfail was being given a debugloc claiming to have been inlined again. This was causing a sitaution where we'd have debug info forfunctionA owning an instruction which claimed it was owned by a different function. Fix this by first checking if the `LastScope` was already inlined and, if so, just used that scope instead.
