Changes to the syntax associated with BoundQueryBody caused slight changes in error span of some rarely reported errors. Update tests.

Preserve Key modifiers from existing anonymous type properties

Fixes #1292

Make the IWorkCoordinatorPriorityService async and appropriately cascade out the asynchrony.

Originally this was synchronous because it was used through codepaths that all were
inherently synchronous.  Over the last year the WorkCoordinator has become increasingly
async, and we're now at the point where this API can be async too.  This is a win for
TypeScript because we have to currently implement this API in blocking fashion.  This
has shown up in profiles, and making it async should be a nice win for us.

Handle using static

Make the portable ResultProvider DLLs portable

We created the CoreSystem projects to ensure that we wouldn't take
dependencies on non-portable APIs.  Now that the ResultProviders are
really portable, they enforce this requirement directly.

Prior to this commit, they were identical to the corresponding desktop
(i.e. NetFx20) assemblies but now all the pieces are in place to compile
them as portable assemblies.

Cleverness: Move resources into the portable projects and link them into
the corresponding desktop projects.  The desktop projects can compile
portable designer files, but not vice versa.

Make the EE-generated module name no longer fixed.

Handle the case where we are passed a type instead of a namespace (using
static).
