Issue Description:

LLDB is often unusable:

error: Couldn't materialize: can't get size of type

error: errored out in DoExecute, couldn't PrepareToExecuteJITExpression

Steps to reproduce the issue:

  1. Create a project using Master-Detail App template in Xcode 11.0 beta 4.
  2. Add a breakpoint in `MasterViewController.insertNewObject(_🙂`.
  3. Type `p tableView.indexPathForRow(at: .zero)` in LLDB when the breakpoint is hit.

I also attached the sample project for convenience.

I have a local patch where `po` now does the right thing. Screenshot attached.

`p` still needs some love, and it's more complicated to fix.
