John Stiles ff6c5bf5ed Generate more diagnostics from IRGenerator, when given bad code.
Two minor changes:
- Converting a Block with bad statements will now generate a partial
  block instead of nullptr.

The change mirrors how DSL behaves; functions containing invalid
statements will now be created and added to the program. Previously, we
would discard a function definition with any invalid statements inside;
this prevented duplicate-function-definition errors from appearing.

- Converting a return with a bad expression will now generate a
  poisoned return instead of nullptr.

This change improves diagnostics for functions with invalid return
statements. If we eliminate the return statements (by returning null),
we report bad return statements as "function can exit without returning
a value" (which is confusing).
