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.
