c++: cast to array of unknown bound [PR93259]
We already know to treat a variable of array-of-unknown-bound type as
dependent, we should do the same for arr{}.
PR c++/93259
gcc/cp/ChangeLog:
* pt.cc (type_dependent_expression_p): Treat a compound
literal of array-of-unknown-bound type like a variable.
gcc/testsuite/ChangeLog:
* g++.dg/cpp0x/initlist-array17.C: New test.
