Subject: [PATCH 1/2] Expand invalid PCM diagnostic
Summary:
When a PCM file is loaded, it can go wrong in various ways. The current
diagnostic only produces the name of the malformed PCM, not why
it is malformed. Expand the diagnostic to display what went wrong!
There is only one call site for this diagnostic, and it
already passes the error message.
Test Plan:
The modified LIT test.
