<pre>[Cocoa] Clean up m_isEmoji in FontPlatformData
https://bugs.webkit.org/show_bug.cgi?id=145644

Patch by Myles C. Maxfield &lt;mmaxfield@apple.com&gt; on 2015-06-04
Reviewed by Andreas Kling.

m_isEmoji used to be a public member variable only defined on iOS. This
means that, whenever it was consulted, the sites were surrounded by
PLATFORM(IOS) guards. A cleaner design is to use a getter and setter,
which on non-iOS platforms, always return false / do nothing. Then, the
use sites can just use these functions without having ugly guards.

No new tests because there is no behavior change.

* platform/graphics/FontPlatformData.h:
(WebCore::FontPlatformData::hash): Simplify isEmoji use site.
(WebCore::FontPlatformData::isEmoji): Getter. Returns false on Mac.
(WebCore::FontPlatformData::setIsEmoji): Setter. Does nothing on Mac.
* platform/graphics/cocoa/FontCascadeCocoa.mm:
(WebCore::pointAdjustedForEmoji): Simplify isEmoji use site.
(WebCore::FontCascade::drawGlyphs): Ditto.
* platform/graphics/cocoa/FontCocoa.mm:
(WebCore::Font::platformInit): Ditto.
(WebCore::canUseFastGlyphAdvanceGetter): Ditto.
(WebCore::isEmoji): Deleted.
* platform/graphics/cocoa/FontPlatformDataCocoa.mm:
(WebCore::FontPlatformData::platformDataInit): Simplify isEmoji use
site.
(WebCore::FontPlatformData::platformDataAssign): Ditto.
(WebCore::FontPlatformData::platformIsEqual): Ditto.
(WebCore::FontPlatformData::ctFontSize): Ditto.
* platform/graphics/ios/FontCacheIOS.mm:
(WebCore::FontCache::getSystemFontFallbackForCharacters): Ditto.
(WebCore::FontCache::createFontPlatformData): Ditto.
* platform/graphics/mac/ComplexTextController.cpp:
