SPV_FAILED_MATCH error mutes DiagnosticStream.
The DiagnosticStream will not emit the accumulated message
text if the error is SPV_FAILED_MATCH.
Change various interfaces to accept the intended error
code instead of a boolean "is_optional". This allows
us to avoid repeating the following type of logic deep
inside helper methods:
if (is_optional) return SPV_FAILED_MATCH;
return diagnostic() << " message text ";
