This doesn't involve any Makefile change so should be relatively safe.
This is needed for:
* BUILTIN_FUNCTION_EMULATION (r773,774), blocker for 665578
* extensions validation in shaders (r745), blocker for 684853
* major performance improvements and bug fixes
Just an ANGLE update, plus updating the list of failed tests on WinXP, also now properly reporting on unexpeced success (using todo(true) instead of ok(false))
This ANGLE update fixes bugs, brings large performance improvements, and adds major new features that web devs are looking forward to: vertex shader texture lookup and float textures.

This update is also needed because the version we're currently using is the chrome_m10 branch and that's no longer maintained. This update will make it much easier to apply security fixes if needed.
