results in them (which we were doing intentionally as a stopgap).  Fix
an DeclContext lookup-table ordering problem which was causing UsingDecls to
show up incorrectly when looking for ordinary results.  And oh hey
Clang-Code-Syntax passes now.

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.

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.
