assert: add support for Map and Set in deepEqual

assert.deepEqual and assert.deepStrictEqual currently return true for
any pair of Maps and Sets regardless of content. This patch adds
support in deepEqual and deepStrictEqual to verify the contents of Maps
and Sets.

Deeo equivalence checking is currently an
O(n^2) operation, and worse, it gets slower exponentially if maps
and sets were nested.

Note that this change breaks compatibility with previous versions of
deepEqual and deepStrictEqual if consumers were depending on all maps
and sets to be seen as equivalent. The old behaviour was never
documented, but nevertheless there are certainly some tests out there
which depend on it.

Support has stalled because the assert API was frozen, but was recently
unfrozen in CTC#63.

---

Later squashed in:

This change updates the checks for deep equality checking on Map and Set
to check all set values / all map keys to see if any of them match the
expected result.

This change is much slower, but based on the conversation in the pull
request its probably the right approach.

assert: fix premature deep strict comparison

Refactors _deepEqual and fixes a few code paths that lead to
behaviors contradicting what the doc says. Before this commit
certain types of objects (Buffers, Dates, etc.) are not checked
properly, and can get away with different prototypes AND different
enumerable owned properties because _deepEqual would jump to
premature conclusion for them.

Since we no longer follow CommonJS unit testing spec,
the checks for primitives and object prototypes are moved
forward for faster failure.

Improve regexp and float* array checks:

* Don't compare lastIndex of regexps, because they are not
  enumerable, so according to the docs they should not be compared
* Compare flags of regexps instead of separate properties
* Use built-in tags to test for float* arrays instead of using
  instanceof

Use full link to the archived GitHub repository.

Use util.objectToString for future improvements to that function
that makes sure the call won't be tampered with.
