Prefer a likely literal over anonymous type in --noImplicitAny codefixes (#36015) * Prefer a likely literal over anonymous type in --noImplicitAny codefixes Before trying to make an anonymous type for a type's usage, we'll first check if there is exactly one builtin primitive the usage is assignable to, and use it if so. Right now that's only `number` and `string` because `boolean` has no distinguishable members. A couple of implementation details: * `tryInsertTypeAnnotation` needed to know to insert a type _after_ a node's `exclamationToken` if it exists * This code area was written before `??` :wink: * Used unknown/any instead of void when applicable * Fix little whitespace change in tests/cases/fourslash/codeFixInferFromUsagePropertyAccessJS.ts * Undid some now-unnecessary unknown additions * Took advice on restricting void to just call expressions 2020-04-22 20:28:11 +02:00			`/// <reference path='fourslash.ts' />`
