Revert of Enforce clearing renderers' paint invalidation state

Revert of Enforce clearing renderers' paint invalidation state (https://codereview.chromium.org/389573008/)

Reason for revert:
Causing consistent assertion failures on Mac.  See e.g. http://build.chromium.org/p/chromium.webkit/builders/WebKit%20Mac10.6%20%28dbg%29/builds/16532/steps/webkit_tests/logs/stdio .  A sample stack:

Original issue's description:
> Enforce clearing renderers' paint invalidation state
> 
> The ASSERT checks that no flags cleared by clearPaintInvalidationState()
> is still set up after calling repaint-after-compositing-update.
> 
> The ASSERT is skipped for SVG subtree as we have an optimization that
> skips them. We could reproduce the exact condition but it seems not
> very useful to do so.
> 
> The change caught several bugs (yay!):
> - one in shouldCheckForPaintInvalidationAfterLayout()
> that made the ASSERT trip on fast/repaint/table-row.html.
> - one where setShouldDoFullPaintInvalidationAfterLayout didn't
> mark the containing block chain for invalidation.
