Eg. program can backup and restore state changing the state object and we want to release program on the correct one
This ensure program is released correctly when there are declaration emit errors during tsc --build
* Extra tests in preparation for lazy signature making sure the original intent of test is maintained
* Whenver we cant use state delay signature calculation and use source file version as signature
* Incremental correctness checks
* Retain old behavior in compile on save by disabling use of file version as signature in when state is not reused
* Emit buildinfo when there are errors with noEmitOnError?
TODO: --build mode
* Always emit tsbuild info even if there are non syntax errors in tsc --build mode
* Sort affectedFilesPendingEmit for consistent build info text
