Layout test fast/css/tagname-and-namespace-case-sensitivity-xml-in-html.html is flakily crashing in WebCore::GLContextGLX::~GLContextGLX(). First recorded crash is r220556 from five days ago, though that's surely not to blame. Can someone check which of the TextureMapper/GLContext refactorings were likely to have introduced this crash?
I'll add a crash expectation for this test, but I'm sure we'll find more affected tests sooner or later.

In loader/load-defer.html today: https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20(Tests)/r220823%20(2663)/results.html (same backtrace).
I'm pretty sure I've seen it in a bunch of other tests as well.

We need to remove the crash expectation, then.
