Avoid an unnecessary recursive loop between type canonicalization and NNS canonicalization which would (rarely) lead to memory corruption. While I'm here, simplify. Fixes PR12166. Not committing a testcase because it's impossible to reduce it.

Frontend: Default to creating output files using temporary files + rename.
...
- This is a more reliable default, as it behaves better on failure and also
ensures that we create *new* files (instead of reusing existing inodes). This
is useful for other applications (like lldb) which want to cache inode's to
know when a file has been rewritten.
