This test case has a DrawRecord in the middle of it.  There was some
hope previously that because this fuzzer memset all the memory it
was allocating, then all the unwritten memory could be consistent.
However, because a bunch of other memory gets allocated when serializing
then that memory can have garbage in the padding.  When simple ops
memcpy as a part of serializing or deserializing, they bring along
that garbage, which can cause binary differences.

This was lucky that this has ever worked on Skia serialization, so
remove the binary comparison and just use the logical comparison.

In a previous CL, we moved the security chip label left by 2dp to align
with URLs in the case where we have an unlabeled lock icon.

However, in doing so, we accidentally un-aligned the indented search
keyword label with the suggestions text.

This CL fixes that.

As far as I can tell, in the old pre-Refresh world, the extra internal
spacing used for the search keyword provider just matched the value of
GetPrefixedSeparatorWidth() as a matter of coincidence.

This CL divorces those two for post-Refresh, because
"something's gotta give".

The MVC refactor for UrlBar.java:
https://chromium-review.googlesource.com/1148680
converted empty text strings to pass in SCROLL_BEGIN.

The logic for properly scrolling empty RTL text existed
only within SCROLL_TO_TLD.  This moves and unifies the
logic within the SCROLL_BEGIN handling.

This also fixes some issues with resetting the previous
scroll state too aggressively so that multiple calls
would need to recalculate.

Overwriting deleted values with cleared values potentially revives
buckets in collections. For atomic garbage collections this is not a
problem as those values are filered out in the visitors already. For
incremental garbage collections the deleted values may be introduced by
erasing a value from a container after it has been visited by the
incremental marker.

It seems this code may be responsible for performance regression in the
linked bug. This CL makes the code conditional on the blink gen property
trees flag (it's unneeded without the flag) to make sure its really the
cause of the regression. We can investigate performance improvements if
it's confirmed.
