Code

Promise.resolve.call(1)           // Compiles without error, throws in runtime
Promise.resolve.call(Promise, 1); // Compile-time error, works fine in runtime

Expected behavior:

• Promise.resolve.call(1) should trigger a compile-time error
• Promise.resolve.call(Promise, 1) should compile

Actual behavior:

The situation is reversed. The one that works in runtime does not compile. The one that does compile throws a runtime error.

• Promise.resolve.call(1) compiles without error, throws Uncaught TypeError: PromiseResolve called on non-object in runtime
• Promise.resolve.call(Promise, 1) gives a compile-time error (Expected 1 arguments, but got 2.), works fine in runtime (returns a Promise<number>)

I'm using "lib": ["dom", "esnext"], "target: "es2015". Tested on Chrome 72.0.3626.121, V8 7.2.502.28.
