<p>Constructs a new Map. A Map is a container that is used to implement map
fields on message objects. It closely follows the ES6 Map API; however,
it is distinct because we do not want to depend on external polyfills or
on ES6 itself.</p>

<div class="description">
<p>Internal map: stores mapping of (string form of key) -> (key, value)
pair.</p>
<p>We provide map semantics for arbitrary key types, but we build on top
of an Object, which has only string keys. In order to avoid the need
to convert a string key back to its native type in many situations,
we store the native key value alongside the value. Thus, we only need
a one-way mapping from a key type to its string form that guarantees
uniqueness and equality (i.e., str(K1) === str(K2) if and only if K1
=== K2).</p>
