Geoffrey Garen 10fc66526a GraphicsLayer::setName() causes heap fragmentation ... https://bugs.webkit.org/show_bug.cgi?id=225838 Reviewed by Simon Fraser. Profiling for heap fragmentation shows that GraphicsLayer::setName() is a top contributor. Worth about 5MB maximum on GMail. Use MAKE_STATIC_STRING_IMPL for our constant layer names so we end up with only one copy and no heap allocation in the many cases that are compile-time constants.
