First pass at fixing issue #1045 to properly detect IE11.
Update ua tests in yui for ie 11 ua fix.
Added Promise performance tests
Merge branch 'issue1045' into dev-master
Build and simpleyui files for issue1045 fix.
resolves #1062 - fix loader test that checks for bleeding dependencies

We only check that the arrays contain the same items. We do not care
about the order of modules in the flattened dependency tree since that's
not guaranteed to be the same across browsers.

We now include nodejs and IE8 since that was the original UA coverage
intent of this test.
