Add dummy key methods for UBSan RTTI. Chromium UBSan builds require RTTI, for which GCC/Clang requires each class' first non-inline virtual method (the "key method") to have a known definition so that its address can be used as a unique type identifier: https://gcc.gnu.org/onlinedocs/gcc/Vague-Linkage.html libEGL and libGLESv2 each use objects who's full definition only exists within one or the other. Methods for which the definition is unknown can still be called if they are virtual, because the compiler/linker only needs to know the vtable entry offset. But because of the GCC/Clang requirement of having the first non-inline virtual method be fully defined, we need to add dummy virtual methods and their definitions.

SwiftShader is a high-performance CPU-based implementation of the OpenGL ES and Direct3D 9 graphics APIs12. Its goal is to provide hardware independence for advanced 3D graphics.
The SwiftShader libraries act as drop-in replacements for graphics drivers.
On Windows, most applications can be made to use SwiftShader's DLLs by placing them in the same folder as the executable. On Linux, the LD_LIBRARY_PATH environment variable or -rpath linker option can be used to direct applications to search for shared libraries in the indicated directory first.
