Disable support for swapped out RenderFrame(Host) and add instrumentation

This CL is aiming to collect information about cases where the
FocusController's focused frame is set to a RemoteFrame. This is the root
cause of the crash in https://crbug.com/541578.

Hey Daniel,
Can you review this CL for me? It is disabling swapped out again and adding a
DumpWithoutCrashing to catch what case we have that is setting the focused frame
to a remote one.
Thanks in advance!
Nasko

+rsesek, it should be safe to call DumpWithoutCrashing on all platforms now,
right? https://crbug.com/349600 is the issue I'm thinking of, but wanted to make
sure I'm not missing something else.

[dcheng, 2015-10-13 00:23:15]

actual change lgtm, let's just make sure DumpWithoutCrashing is in fact, not
crashing =)

A revert of this CL (patchset #2 id:20001) has been created in

The reason for reverting is: There are enough dumps at this time and this CL is
no longer needed..
