Format function type (and others)

[saschanaz]

Fixes #4438 and (maybe) #4486.

Async-await current:

async   function asyncFunction() {
    await
    Promise.resolve("await");
    return await   Promise.resolve("completed");
}

Fix:

async function asyncFunction() {
    await
        Promise.resolve("await");
    return await Promise.resolve("completed");
}

Function type / Constructor type current:

function renderElement(
    renderNode:
    (
    node: Node
    ) => void,
    newNode:
    new (
    name: string
    ) => Node
): void {
}

Fix:

function renderElement(
    renderNode:
        (
            node: Node
        ) => void,
    newNode:
        new (
            name: string
        ) => Node
): void {
}

Parenthesized type current:

function foo(
    bar:
    (
    boolean
    )
) {
}

Fix:

function foo(
    bar:
        (
            boolean
        )
) {
}

Call/Constructor/Method signature current:
(Constructor signature only is covered)

type Foo = {
    (
        call: any
    ): void;
    new (
    constr: any
    ): void;
    method(
        whatever: any
    ): void;
};

Fix:

type Foo = {
    (
        call: any
    ): void;
    new (
        constr: any
    ): void;
    method(
        whatever: any
    ): void;
};

Tagged template string current:

String.raw`foo`
String.raw  `bar${3}`
String.raw
`template`

Fix:

String.raw `foo`
String.raw `bar${3}`
String.raw
    `template`

Type alias current:

type   Alias =
number;

Fix:

type Alias =
    number;

Type union current:

type   Union = number  |  {}
|string

Fix:

type Union = number | {}
    | string

• Fix parenthesized type formatting
• Add tests

[mhegazy]

we should also add:

• ConstructorType
• ConstructSignature
• CallSignature
• ParenthesizedType
• TaggedTemplateExpression
• AwaitExpression
• YieldExpression

[mhegazy]

and add tests for theses :)

[saschanaz]

@mhegazy I think most of the types are now covered except YieldExpression. Do you have an example that is not being properly formatted?

Thanks @saschanaz!

@mhegazy should this be brought into 1.6 as well?
