TestExpectations for handful of tests flakily hitting assert

Do not repaint the overhang linen texture every frame

Instead of adding a layer for the linen texture (which needs to
be painted every frame) specify a gutter texture for the layer
tree to use.

Remove the layer into which the linen texture was being painted.

Remove the overflow related functions from RenderLayer

I inspected the call sites for NULL ScrollableArea and they
should be safe. Also removed RenderLayer::scroll().

Simplify SVG's styleDidChange

This is a merge of wkbug.com/123108 by Andreas Kling <akling@apple.com>.

SVG's styleWillChange code can me moved into styleDidChange which both
simplifies this code and removes a few virtuals. This patch also merges
RenderSVGBlock::styleWillChange into RenderSVGBlock::styleDidChange
which was not in the WebKit patch.

No new tests, covered by existing tests.

Added run-perf-test.cfg and PRESUBMIT.py. The bisect/perf bots work by modifying a .cfg file with the parameters of the job (ie. revision, command, repetitions, etc...) and submitting that as a patch to the bot. Since a single patch can't span both blink and chromium, we need a run-perf-test.cfg in each depot that we're likely to try running perf tests from.
