Make landmines work on the first landmine.
With the original script, landmines don't work if the initial commit of the landmine script and the first landmine are in the same build. In this case, the landmine file wouldn't exist yet and no landmine would be triggered. But the updated landmine content would have still been written, omitting the landmine.
Now, the script will initialize an empty landmine file if none exists. This will make sure that a landmine is set on the branch builders after the next branch point.
This also adds some debugging output to better trace when landmines are set/deleted.

The android_webview get's it's compiler flags from the Android build system,

The stub cache used kHeapObjectTagSize to scale indices, but there

Make GCTracer persistent.
This is essentially https://codereview.chromium.org/
390823003/. It turns
out that it's safe to use a persistent GCTracer instead
of creating and destroying GCTracers for each GC, because
Scavenge and Mark-Sweep steps never overlap, and the tracking of
incremental marking also happens separately for the two types of GC.
Tracking of incremental marking will be moved into the GCTracer in a
follow-up patch.

DetachGlobal detaches original context of a global proxy object.
Before this patch, the constructor JSFunction still carried a reference to the old context after |Bootstrapper::DetachGlobal| call.
This patch removes the reference by setting the constructor null.
