This commit fixes an issue when pipelining mode is used in handling recompilations. Previously a sequence of compilations could look like: * Crate A starts to build * Crate A produces metadata * Crate B, which depends on A, starts * Crate B finishes * Crate A finishes In this case the mtime for B is before that of A, which fooled Cargo into thinking that B needed to be recompiled. In this case, however, B doesn't actually need to be recompiled because it only depends on the metadata of A, not the final artifacts. This unfortunately resulted in some duplication in a few places, but not really much moreso than already exists between fingerprinting and compilation.
