Error output: difficult to understand multistorey errors

### Incompatible type ```ts var foo = {a: {b: {c: {d: 3}}}}; var bar: {a: {b: {c: {d: {e: number}}}}} = foo; ``` Instead of ``` Type '{ a: { b: { c: { d: number; }; }; }; }' is not assignable to type '{ a: { b: { c: { d: { e: number; }; }; }; }; }'. Types of property 'a' are incompatible. Type '{ b: { c: { d: number; }; }; }' is not assignable to type '{ b: { c: { d: { e: number; }; }; }; }'. Types of property 'b' are incompatible. Type '{ c: { d: number; }; }' is not assignable to type '{ c: { d: { e: number; }; }; }'. Types of property 'c' are incompatible. Type '{ d: number; }' is not assignable to type '{ d: { e: number; }; }'. Types of property 'd' are incompatible. Type 'number' is not assignable to type '{ e: number; }'. ``` Print something like that ``` Type '{ a: { b: { c: { d: number; }; }; }; }' is not assignable to type '{ a: { b: { c: { d: { e: number; }; }; }; }; }'. Property 'a.b.c.d: number' is not assignable to 'a.b.c.d: {...}' ``` ### Missing property ```ts var foo = {a: {b: {c: {d: 3}}}}; var bar: {a: {b: {c: {d: number, e: number}}}} = foo; ``` ``` Type '{ a: { b: { c: { d: number; }; }; }; }' is not assignable to type '{ a: { b: { c: { d: number; e: number; }; }; }; }'. Types of property 'a' are incompatible. Type '{ b: { c: { d: number; }; }; }' is not assignable to type '{ b: { c: { d: number; e: number; }; }; }'. Types of property 'b' are incompatible. Type '{ c: { d: number; }; }' is not assignable to type '{ c: { d: number; e: number; }; }'. Types of property 'c' are incompatible. Type '{ d: number; }' is not assignable to type '{ d: number; e: number; }'. Property 'e' is missing in type '{ d: number; }'. ``` vs ``` Type '{ a: { b: { c: { d: number; }; }; }; }' is not assignable to type '{ a: { b: { c: { d: number; e: number; }; }; }; }'. Property 'a.b.c.e: number' is missing ``` ### Incompatible function para…
