Add ASAN=1 to the build system.
Just use `ASAN=1 make test_grep` or whatever. You'll probably want to set $ASAN_SYMBOLIZER_PATH to point to llvm-symbolizer, but Debian makes that annoying by calling the symbolizer /usr/bin/llvm-symbolizer-4.0 or whatever, and ASan refuses to use it: ==43370==ERROR: External symbolizer path is set to '/usr/bin/llvm-symbolizer-4.0' which isn't a known symbolizer. Please set the path to the llvm-symbolizer binary or other known tool. My usual workaround for this is to drop an llvm-symbolizer symlink in the current directory, and I'm happy to automate that in the script to make it require no knowledge of any of this nonsense, but haven't done so in this initial patch. I tested that this is actually working by reverting the grep fix and running `ASAN=1 make test_grep`.
