    middle-end/121216 - ICE with VLA const string initializer

    constant_byte_string fails to consider the string type might be VLA
    when initialized by an empty string CTOR.

            PR middle-end/121216
            * expr.cc (constant_byte_string): Check the string type
            size fits an uhwi before converting to uhwi.

            * gcc.dg/pr121216.c: New testcase.
