    c++: dependent array bounds completion [PR104302]

    The patch for PR55227 changed the minimal init-list handling in
    cp_complete_array_type to a call to reshape_init, which broke on the
    dependent initializer.  It occurred to me that trying to deduce the array
    size from a dependent init-list is wrong in general, so let's just not.  I
    also limited the reshape_init call to the case of a char array, as before
    the patch for 55227; that's the only case where we want to strip a level of
    braces from an array.

            PR c++/104302

    gcc/cp/ChangeLog:

            * decl.cc (maybe_deduce_size_from_array_init): Give up
            on type-dependent init.
            (cp_complete_array_type): Only call reshape_init for character
            array.

    gcc/testsuite/ChangeLog:

            * g++.dg/template/array35.C: New test.
            * g++.dg/template/array36.C: New test.
