Add a heuristic to the dead stores checker to prune dead stores for variables annotated with '__block'.  This is overly conservative, but now the analyzer doesn't report dead stores for variables that can be updated by a block call.

that it doesn't have dangling pointers when abstract types are resolved. This
modifies it somewhat to address comments: making the "StructLayoutMap" an
anonymous structure, calling "removeAbstractTypeUser" when appropriate, and
adding asserts where helpful.

be annoying.  I'm working on this next.  WIP.

file. This is accomplished by introducing the notion of a "virtual"
file into the file manager, which provides a FileEntry* for a named
file whose size and modification time are known but which may not
exist on disk.

Added a cute little test that remaps both a .c file and a .h file it
includes to alternative files.

In Sema, whenever we think that a function is going to cause a vtable to be generated, we mark any virtual implicit member functions as referenced.
