BUG=v8:3521

[smikes, 2014-08-19 03:20:55]

Patch to implement 'harmony' in context for test runners.

Unfortunately this changeset includes the entire contents of the previous (3513)
changeset

https://codereview.chromium.org/486853004/diff/1/test/test262/harness-adapt.js
File test/test262/harness-adapt.js (right):

https://codereview.chromium.org/486853004/diff/1/test/test262/harness-adapt.j...
test/test262/harness-adapt.js:83: 
This patchset replicates the contents of v8:3513

(https://codereview.chromium.org/478163002/)

I will amend it once 3513 lands; for now 3521 should be considered blocked by
3513.

I don't think we need this. The harmony-related tests will start passing when
the respective features are enabled by default, which IMHO is good enough.

Fair enough.  I'll leave it here, and when harmony features start landing
 (or more tests start covering harmony), if you decide you want it, here it is.
