* Properly infer `this` in tagged `@constructor`s.
`c.prototype.method = function() { this }` was already supported.
This commit add support to two more kinds relying on the JSDoc
`@constructor` tag. These are:
1. `/** @constructor */ function Example() { this }`
2. `/** @constructor */ var Example = function() { this }`
* Update the baseline for js constructorFunctions.
C3 and C4 `this` was set as `any`, now it is properly showing as
the class type.
* Fix lint errors
* Add circular initialisers to constructo fn tests.
* Error (`TS2348`) if calling tagged js constructors
When calling a JS function explicitly tagged with either `@class` or
`@constructor` the checker should throw a TS2348 not callable error.
* Don't resolve jsdoc classes with construct sigs.
This undoes the last commit that sought to change how js functions
tagged with `@class` were inferred. For some reason, currently
unknown, giving those functions construct signatures causes issues
in property assignment/member resolution (as seen in the
`typeFromPropertyAssignment12` test case).
Instead of changing the signature resolution, the error is explicitly
generated in `resolveCallExpression` for those functions.
