new loplugin mergeclasses

Idea from Norbert (shm_get) - look for classes that are
(a) not instantiated
(b) have zero or one subclasses
and warn about them - would allow us to remove a bunch of abstract
classes that can be merged into one class and simplified

+Idea from Norbert (shm_get) - look for classes that are
+(a) not instantiated
+(b) have zero or one subclasses
+and warn about them - would allow us to remove a bunch of abstract classes
+that can be merged into one class and simplified.
+
+Dump a list of
+- unique classes that exist (A)
+- unique classes that are instantiated (B)
+- unique class-subclass relationships (C)
+Then
+   let D = A minus B
+   for each class in D, look in C and count the entries, then dump it if no-entries == 1
+
+The process goes something like this:
+  $ make check
+  $ make FORCE_COMPILE_ALL=1 COMPILER_PLUGIN_TOOL='mergeclasses' check
+  $ ./compilerplugins/clang/mergeclasses.py > mergeclasses.results
+
+FIXME exclude 'static-only' classes, which some people may use/have used instead of a namespace to tie together a bunch of functions
