Add missing release notes for 1.8.12, 1.8.13, 1.8.14

I found those in HTML only on the Eclipse web server, but not in the Git
repository. So, I manually converted them to ADOC.

+_Release info: 1.8.12 available 20-Oct-2017_
+
+This is a small release that includes a backport of some 1.9.0 work that improves the performance of Spring AOP (or any
+system consuming AspectJ in a similar way to Spring).
+
+Dave Syer recently created a series of benchmarks for checking the speed of Spring-AspectJ:
+https://github.com/dsyer/spring-boot-aspectj
+
+Here we can see the numbers for AspectJ 1.8.11 (on an older Macbook Pro):

+StartupBenchmark.spring   a20_100  avgt   10  11.497 ~ 0.162   s/op
+....
+
+So this is the average **startup time** of an app affected by aspects applying to the beans involved. Where numbers are
+referenced the first is the number of aspects/pointcuts and the second is the number of beans. The 'a' indicates an
+annotation based pointcut vs a non-annotation based pointcut ('v'). Notice things are much worse for annotation based
+pointcuts. At 20 pointcuts and 50 beans the app is 9 seconds slower to startup.
+
+In AspectJ 1.8.12 and 1.9.0.RC1 some work has been done here. The key change is to recognize that the use of annotations
+with runtime retention is much more likely than annotations with class level retention. Retrieving annotations with
+class retention is costly because we must open the bytes for the class file and dig around in there (vs runtime
+retention which are immediately accessible by reflection on the types). In 1.8.11 the actual type of the annotation
+involved in the matching is ignored and the code will fetch *all* the annotations on the type/method/field being matched
+against. So even if the match is looking for a runtime retention annotation, we were doing the costly thing of fetching
+any class retention annotations. In 1.8.12/1.9.0.RC1 we take the type of the match annotation into account - allowing us
+to skip opening the classfiles in many cases. There is also some deeper work on activating caches that were not
+previously being used correctly but the primary change is factoring in the annotation type.
+
+What difference does that make? AspectJ 1.8.12:

+Look at the a20_100 case - instead of impacting start time by 9 seconds, it impacts it by 1 second.

+_Release info: 1.8.13 available 15-Nov-2017_
+
+Small release that:
+
+  * Dials back the performance optimizations for Spring AOP. One of them was taking things too far and has caused an
+    issue link:https://jira.spring.io/browse/SPR-16161[SPR-16161]. This wasn't the main performance enhancement for
+    Spring AOP though so the numbers are still very close to those shown in the 1.8.12 readme.
+
+  * Includes better toleration of new JDK versions. If the versions are coming out thick and fast we need older
+    AspectJs to cope when simply running on new JDKs they haven't encountered before.

+_Release info: 1.8.14 available 6-Mar-2019_
+
+Small release that:
+
+ * Will skip `module-info.class` and class files under `META-INF` that you find in multi-release JARs, as described in
+   link:https://bugs.eclipse.org/bugs/show_bug.cgi?id=545033[bug 545033]. This enables some usage of AspectJ 8 operating
+   on JARs containing some of these features from later Java (but where the main set of classfiles in a JAR are Java 8
+   or lower). For proper treatment of Java 9 code, please use AspectJ 1.9 or later.
