This reverts commit 6da88ec19eea2780c030dc95fcc55d059fed69e5.
Removing existing handlers turns out to be load-bearing for Jasmine's
parallel mode. ParallelWorker (in the jasmine package) installs a pair
of handlers before booting core so that it can catch late async errors
that happen after one spec file has finished executing and before the
next starts. If those aren't uninstalled, errors that get routed through
jasmine-core's normal error handling mechanism will also be reported
via ParallelWorker's handlers. It might be possible for ParallelWorker
to uninstall and install its handlers at the right time, but it's
likely that there would be gaps in between when core uninstalls its
handlers and when ParallelWorker installs. And in any case, the
old behavior of GlobalErrors was a perfect match for what ParallelWorker
needs, so let's keep it.
This:
* Sets the stage for getting suite and spec execution in one place
* Greatly simplifies the interaction between Runner and TreeProcessor
* Focuses TreeProcessor more on building execution trees
These are mostly adaptations of the execution tests from TreeProcessorSpec.js.
They are meant to support refactoring of the interface and responsibility
division between Runner and TreeProcessor. All these scenarios are probably
covered by nearly-end-to-end integration tests, but those are more difficult
to debug.
All current shipped versions of zone.js contain a monkey patch that fails
to pass constructor arguments on to GlobalErrors. That would crash Jasmine
if it was applied early enough to have any effect.

This commit attempts to ensure that the timers created by jasmine mock
clock do not conflict with the native timers. This also retains
pre-existing behavior whereby a native scheduled function cannot be
cleared if it was created prior to the mock clock being installed
(unless the mock clock is uninstalled first).
Prior to this commit, attempting to clear a native timer would result in
clearing a mocked scheduled function instead, in some scenarios where
the IDs conflicted.
