jQuery's elem.html('') is way slower than elem.empty(). As clearing
element contents happens quite often in certain scenarios, switching
to using .empty() provides a significant performance boost when using
Angular with jQuery.
Closes#4457
Change the a directive to link and hookup a click event only when
there is no href or name in the template element.
In a large Google app, this results in about 800 fewer registrations,
saving a small but measurable amount of time and memory.
Closes#5362
Replace calls to angular.copy with calls to a new function, shallowClearAndCopy.
Add calls to copy for cache access in $http in order to prevent modification of cached data.
Results in a measurable improvement to the startup time of complex apps within Google.
Closes#5300
Updates isDate et al to use call instead of apply and === instead of ==.
The change to call brings minor performance improvement and === is just
better practice than ==.

When a component uses an isolate scope reference
and the the component is used with an object literal
a new object is created on every evaluation.
Therefore the compiler needs to compare
the values of the parent and the isolate scope
using object equality and not object reference
equality.
Fixes#5296.
Copy mock data returned from the mock $httpBackend.
This prevents modifications to the response from affecting future responses.
Previously, this misbehavior was being mitigated by the deep copy in $resource, but that no longer exists.
Instead of parallelization on a single Travis VM, we use two VMs.
- output is nicer (we don't have to buffer e2e tests and then show it at the end)
- you can easily see faster the result of unit tests (as it's basically a separate build)
We should also make sure we only do the necesary stuff (for install we don't need to do `grunt
package` for unit tests, we only need to generate the docs for e2e tests.
Just my first pass at a more readable format of the guide index.
Note: the styles apply to all content in the docs, not just the guide
index. This is intentional and I feel that the result is positive.
Change position of <a> and <li> tags in tutorial nav buttons
partial. This allows the full area of the button to be clicked
rather than just the text.

Instead of using fix() or chore() when labelling a commit which improves
speed or performance use perf(). Perf commits will be listed in the
CHANGELOG under "Performance Improvements".
For example:
perf($animate): cache all getComputedStyle operations to reduce additional reflows
If an element has a directive whose content is loaded using `templateUrl`,
and the element is cloned using a linking function before the template arrives,
the clone needs to be updated as well.
This also updates `ngIf` and `ngRepeat` to keep the connection to the clone
of a tranclude function, so that they know about the changes a directive with
`templateUrl` does to the element in the future.
Fixes to #4930.
angular.isElement currently returns a truthy object/function, or false. This
patch aims to correct this behaviour by casting the result of the isElement
expression to a boolean value via double-negation.

Stop dirty-checking during $digest after the last dirty watcher has been re-checked.
This prevents unneeded re-checking of the remaining watchers (They were already
checked in the previous iteration), bringing a substantial performance improvement
to the average case run time of $digest.
