...class,

3. The LeakDetector changes: These are not ok, because the order of
construction of the static objects is not defined (these maps may be
initialized after other things that put stuff into them).
If you change the static objects in getObjects() and getLLVMObjects()
to be LLVMObjects themselves instead of pointers, I think everything
should work fine (they will be initialized on first use that way). In
other words, getObjects becomes:
Objects &getObjects() {
static Objects Objs;
return Objs;
}
4. The Types change, including the...

There are ways around this, but it turns into a two-pass operation: loop
over all constants to drop their uses, then
