Simple line layout: Use RenderText::canUseSimpleFontCodePath() only as a hint.
https://bugs.webkit.org/show_bug.cgi?id=167853
<rdar://problem/30367302>

Reviewed by Simon Fraser.

Source/WebCore:

Apparently RenderText::canUseSimpleFontCodePath() only checks if the string is qualified for
the simple font code path. However certain css properties could still force us to use the complex
path.
In most cases, we still do only one string traversal thanks to TextRun::setCharacterScanForCodePath().

(WebCore::SimpleLineLayout::canUseForFontAndText):
