scons: Allow building with Address Sanitizer.
libasan is never linked to shared objects (which doesn't go well with
-z,defs). It must either be linked to the main executable, or (more
practically for OpenGL drivers) be pre-loaded via LD_PRELOAD.
Otherwise works.
I didn't find anything with llvmpipe. I suspect the fact that the
JIT compiled code isn't instrumented means there are lots of errors it
can't catch.
But for non-JIT drivers, the Address/Leak Sanitizers seem like a faster
alternative to Valgrind.
Usage (Ubuntu 15.10):
scons asan=1 libgl-xlib
export LD_LIBRARY_PATH=$PWD/build/linux-x86_64-debug/gallium/targets/libgl-xlib
LD_PRELOAD=libasan.so.2 any-opengl-application
