HIR is removed from this PR, with the minifier being commented out.
HIR is a wonderful idea for compiling to lower languages, but after
sitting on it for a few months I found that it only adds confusion and
uncertainties to both myself and future contributors.
It also adds too much burden to maintainers if we plan to support more
downstream tools.
1 AST is the only way.
Fold constant addition expressions. Handles string concatenation and
addition, both with implicit casting.
For example,
```ts
let x = 1 + 1
let y = "hello " + "world"
```
now becomes
```ts
let x = 2
let y = "hello world"
```
## Extra Goodies
- test(minifier): add `test_snapshot` helper to perform snapshot tests
with `insta`
- up(hir): implement `std::ops::Add` for `NumericValue`
- up(span): impl `TryFrom<Cow<'_, &str>>` for `Atom`
When initially written types were not in the symbol table. Now that
types are in the symbol table it makes sense given
```ts
type A = 1
type B = A
```
that you can get to the symbol id for for A from type B = A.
Please correct me if I'm wrong about how I implemented this. I also
verified that occurrence (I believe this is the correct word) behaves
how I would expect.
```ts
type RecursiveType = string | {[x: string]: RecursiveType}
```
Does populate a reference.

Fixes 11 TS conformance tests and 18 babel tests.
Adds types to the symbol table functionally conformant to TS behavior
but symbol flags implemented slightly differently.
Symbol redeclaration check is also not entirely conformant but fixing
this seems like a separate PR.
For testing purposes - consistent-export-type was also implemented
(WIP).
