[Errors] Message quality degradation for overload resolution errors

[mhegazy]

// @module: commonjs

// @Filename: foo_0.ts

class Foo<T extends {a: string; b:number;}>{

test: T;

constructor(x: T){}

}

export = Foo;

// @Filename: foo_1.ts

import foo = require("./foo_0");

var x = new foo(true); // Should error

var y = new foo({a: "test", b: 42}); // Should be OK

var z: number = y.test.b;

Expected:

!!! Supplied parameters do not match any signature of call target:

!!! Type 'Boolean' is missing property 'a' from type '{ a: string; b: number; }'.

Actual:

‌!!! Supplied parameters do not match any signature of call target.

Sufficiently stripped down:

function foo(x: { a: string }): number {
    return undefined;
}

foo(true);

Reports:

Supplied parameters do not match any signature of call target.
