This slightly degrades the performance of CJS export analysis on subsequent runs because I changed it to no longer cache in the DENO_DIR with this PR (denort now properly has no idea about the DENO_DIR). We'll have to change it to embed this data in the binary and that will also allow us to get rid of swc in denort (will do that in a follow-up PR).
