Update on "[compiler] ValidatePreservedManualMemoization reports detailed errors"

This pass didn't previously report the precise difference btw inferred/manual dependencies unless a debug flag was set. But the error message is really good (nice job mofeiz): the only catch is that in theory the inferred dep could be a temporary that can't trivially be reported to the user.

But the messages are really useful for quickly verifying why the compiler couldn't preserve memoization. So here we switch to outputting a detailed message about the discrepancy btw inferred/manual deps so long as the inferred dep root is a named variable. I also slightly adjusted the message to handle the case where there is no diagnostic, which can occur if there were no manual deps but the compiler inferred a dependency.
