This commit adds `import.meta.filename` and `import.meta.dirname` APIs. These APIs return string representation of filename and containing dirname. They are only defined for local modules (modules that have `file:///` scheme). Example: ```ts console.log(import.meta.filename, import.meta.dirname) ``` Unix: ``` $ deno run /dev/my_module.ts /dev/my_module.ts /dev/ ``` Windows: ``` $ deno run C:\dev\my_module.ts C:\dev\my_module.ts C:\ ``` |

How to upgrade TypeScript.
The files in this directory are mostly from the TypeScript repository. We currently (unfortunately) have a rather manual process for upgrading TypeScript. It works like this currently:
- Checkout denoland/TypeScript repo in a separate directory.
- Add Microsoft/TypeScript as a remote and fetch its latest tags
- Checkout a new branch based on this tag.
- Cherry pick the custom commit we made in a previous release to the new one.
- This commit has a "deno.ts" file in it. Read the instructions in it.
- Copy typescript.js into Deno repo.
- Copy d.ts files into dts directory.
- Review the copied files, removing and reverting what's necessary
So that might look something like this:
git clone https://github.com/denoland/TypeScript.git
cd typescript
git remote add upstream https://github.com/Microsoft/TypeScript
git fetch upstream
git checkout v3.9.7
git checkout -b branch_v3.9.7
git cherry pick <previous-release-branch-commit-we-did>
npm install
