* Skip overloads with too-short function parameters
If the parameter of an overload is a function and the argument is also a
function, skip the overload if the parameter has fewer arguments than
the argument does. That overload cannot possibly apply, and should not
participate in, for example, contextual typing.
Example:
```ts
interface I {
(a: number): void;
(b: string, c): void;
}
declare function f(i: I): void;
f((x, y) => {});
```
This code now skips the first overload instead of considering.
This was a longstanding bug but was only uncovered now that more
functions expressions are context sensitive.

type you want really is the method's type.

When there are property assignments in a the class body of an inheriting
class, tsc current emit the following compilation:
```ts
class Foo extends Bar {
public foo = 1;
}
```
```js
class Foo extends Bar {
constructor(…args) {
super(…args);
this.foo = 1;
}
}
```
This introduces an unneeded local variable and might force a reification
of the `arguments` object (or otherwise reify the arguments into an
array).
This is particularly bad when that output is fed into another transpiler
like Babel. In Babel, you get something like this today:
```js
var Foo = (function (_Bar) {
_inherits(Foo, _Bar);
function Foo() {
_classCallCheck(this, Foo);
for (var _len = arguments.length, args = Array(_len), _key = 0; _key < _len; _key++) {
args[_key] = arguments[_key];
}
_Bar.call.apply(_Bar, [this].concat(args));
this.foo = 1;
}
return Foo;
})(Bar);
```
This causes a lot of needless work/allocations and some very strange
code (`.call.apply` o_0).
Admittedly, this is not strictly tsc’s problem; it could have done a
deeper analysis of the code and optimized out the extra dance. However,
tsc could also have emitted this simpler, more concise and semantically
equivalent code in the first place:
```js
class Foo extends Bar {
constructor() {
super(…arguments);
this.foo = 1;
}
}
```
Which compiles into the following in Babel:
```js
var Foo = (function (_Bar) {
_inherits(Foo, _Bar);
function Foo() {
_classCallCheck(this, Foo);
_Bar.apply(this, arguments);
this.foo = 1;
}
return Foo;
})(Bar);
```
Which is well-optimized (today) in most engines and much less confusing
to read.
As far as I can tell, the proposed compilation has exactly the same
semantics as before.

* Have travis take shallow clones of the repo (#10275)
Just cloning TS on travis takes 23 seconds on linux (68 seconds on mac), hopefully having it do a shallow clone will help.
We don't rely on any tagging/artifacts from the travis servers which clone depth could impact, so this shouldn't impact anything other than build speed.

* Use 'MapLike' instead of 'Map' in 'preferConstRule.ts'.

instanceof and user-defined typeguards narrow from 'any' unless the narrowed-to type is exactly 'Object' or 'Function'. This is a breaking change.

* Update error message for conflicting type definitions
Fixes#10370

Also simply it considerably after noticing that it's *only* called for
Javascript files, so there was a lot of dead code for TS cases that
never happened.
