Issue Description:

It's very common to get errors such as

po thing
error: <EXPR>:3:1: error: use of unresolved identifier 'thing'
thing
^~~~~

or

po thing
error: <EXPR>:1:11: error: use of undeclared type '$__lldb_context'
extension $__lldb_context {
          ^~~~~~~~~~~~~~~

error: <EXPR>:19:5: error: use of unresolved identifier '$__lldb_injected_self'
    $__lldb_injected_self.$__lldb_wrapped_expr_75(
    ^~~~~~~~~~~~~~~~~~~~~

when using LLDB in scopes such as protocol extensions and generic functions.

I've attached a very minimal sample projects for both iOS and a command line Swift app that demonstrate these issues reliably. They both fail in slightly different ways.

There's also a screen recording demonstrating the steps I'm taking to trigger these issues.

These were all fixed in the 5.1 branch.
