[Patch, fortran] PR93833 - [8/9/10 Regression] ICE in trans_array_constructor, at fortran/trans-array.c:2566

[Paul Richard Thomas]

This is yet another case, where a deferred character length variable
loses the character length backend_decl. As previously, converting the
expression and using the string_length recovers it successfully.

Regtested on FC31/x86_64 - OK for trunk, followed by 8- and 9-branches
after a week or two?

    * trans-array.c (get_array_ctor_var_strlen): If the character
    length backend_decl cannot be found, convert the expression and
    use the string length. Clear up some minor white space issues in
    the rest of the file.
