This adds support for computed property names, under the flag
--harmony-computed-property-names, for both object literals and
classes.
This is a revert of the revert, a76419f0f4.
This changes to do an early bailout in
HOptimizedGraphBuilder::VisitObjectLiteral instead of doing that in the later
loop.

The GraphReducer should recurse into new inputs after a node was
changed. Most of the reducers already assume this behavior, and it
mostly worked by accident in many cases.

The spec ended up using Get(unscopables, propertyName) and
comparing the result to undefined instead of using Has.

Reason for revert:
Crashes Win32. It was not flake.

This greatly reduces the number of nodes in the graph (by more than 20x in
some extreme cases) for the Emscripten python interpreter main function.

The bug would occur when we try to Reset() to a position already at the end.
This happens e.g., when the regexp ends with \u. What used to happen in that
case: 1) Advance past \ and u (to the end) (which wouldn't increase next_pos_
enough) 2) Try to parse 4 hex digits 3) When that failed, Reset() to the
position which should've been at the end but wasn't.
To be able to properly Reset() to a position at the end, we need to allow
next_pos_ to move beyond the end (since position() is next_pos_ - 1).
Minimal repro case:
var r = /foo\u/
r.test("foou") // should be true, was false.
(Note that \u not followed by 4 hex didits should be interpreted as an identity
escape. It already worked unless \u was at the end of the regexp.)

[turbofan] Remove the no-context hack for JSToNumber.
The ToNumberStub is now able to handle all plain primitives (Numbers,
Booleans, Null, Undefined and Strings) without context access.

Relanded with fix for always returning Change for PlainPrimitive even
if there was no change. The performance regression on primes.js and
corrections.js is due to unlucky loop header alignment; will be addressed
separately.

The snapshot and natives blob files should be output in the out directory
instead of the gen directory so that they can be picked up by the
