c307bbb3a9 Fix PathHoister hoisting before a same-scope variable declaration. 
Seems we didn't have tests running for this very simple case.

Also fixes #5520

14d3c2e256 Avoid adding unnecessary closure for block scoping (#5246) 
When you write

```
for (const x of l) {
  setTimeout(() => x);
}
```

we need to add a closure because the variable is meant to be block-scoped and recreated each time the block runs. We do this.

However, we also add the closure when no loop is present. This isn't necessary, because if no loop is present then each piece of code runs at most once. I changed the transform to only add a closure if a variable is referenced from within a loop.

eb91bd831c Fix PathHoister hoisting JSX member expressions on "this". (#5143) 
The PathHoister ignored member references on "this", causing it
to potentially hoist an expression above its function scope.

This patch tells the hoister to watch for "this", and if seen,
mark the nearest non-arrow function scope as the upper limit
for hoistng.

This fixes #4397 and is an alternative to #4787.

c438209718 Fix constant elements hoisted before declarator (#4804) 
When multiple declarators are present in a declaration, we want to insert the constant element inside the declaration rather than placing it before because it may rely on a declarator inside that same declaration.

5a9509205b Fix constant elements hoisted out of block (#4419) 
When block scoped variables caused the block to be wrapped in a closure, the variable `bindings` remained in parent function scope, which caused the JSX element to be hoisted out of the closure.

d1b8db1532 React inlining: Refactor to reduce parsing cost 
- Have the `jsx` helper do the `defaultProps` work instead of calling `defaultProps` inline.
- Put `key` after `props` and make it optional.
- Inline `children` as rest args instead of in the object.
- Rename `createRawReactElement` to `jsx`. I wish I was kidding.

Most of these are silly microoptimizations. In my test file (based off an internal RN app), this reduces the parsing overhead of inlining from around 1% to 0.1% in JSC and from 0.6% to 0.0% in V8 (compared to element inlining before this commit).

Once parsed, the initial render with inlining is the same speed as not inlining in JSC and ~1% slower in V8. A second initial render in the same context (reusing the function objects, JIT, etc) is 2.0% faster in JSC and 5.5% faster in V8.
