  Log Message:
  -----------
  [flang] Warn on mismatched DATA substring sizes rather than crashing

When a DATA statement initializes a substring with a character constant
of the wrong length, do the right thing with blank padding or truncation,
and emit a warning.  Current code is crashing due to an unhandled error
reported from the low-level data image initialization framework.
