This should help us avoid landing memory leaks (and some buffer overflows)
throughout the GL stack. I put the asan lib in x86_test-base because
we'll want asan for lavapipe, too.
This requires keeping debug symbols for the asan drivers in the artifacts,
as otherwise you can't do much with the backtraces it produces.
