Creating a js object with `Object.create(null)` produces an empty
js object with no prototype. Calling methods attached to these
objects would result in a NPE since we assumed all objects would
have a valid `.__proto__`.
Discovered the error in some benchmark code. Created a new test
with the same patterns.

Adds tests for JS objects with functions with positional and
optional parameters. It does not include named arguments as those
should be statically disallowed.

This tests static analysis on the ddc patch, but not the dart2js one yet.
It also fixes js/null_test.dart to ensure it passes. Note, that test was broken independent of NNBD.

The `new array.constructor()` pattern is occasionally used in JS
(presumably, to get the array subtype if one is available). GopherJS in
particular does this. This fixes DDC's generic `JSArray<T>` to support
this pattern, for all values of T. This also makes JSArray work like
all other "native" types in DDC, where the "constructor" property
is the JS constructor for that native type.

This type is used for JS instanceof checks. dart.dynamic doesn't work for that. In general, this fall back looks dodgy (with or without this change), but this unblocks an internal user.
