[experimental] Add sanitizer options to LDC.

Browse source 
Add some of the sanitizer passes to LDC. This is not complete (linking must be
done using clang and the right `-fsanitize=` option) and may not be useful at
all.

If it proves to be usefull then a lot of other options (e.g. blacklist) must be
added.
