gimplify: Gimplify value in gimplify_init_ctor_eval_range [PR98353]
gimplify_init_ctor_eval_range wasn't gimplifying value, so if it wasn't
a gimple val, verification at the end of gimplification would ICE (or with
release checking some random pass later on would ICE or misbehave).

PR c++/98353
* gimplify.c (gimplify_init_ctor_eval_range): Gimplify value before
storing it into cref.
* g++.dg/opt/pr98353.C: New test.
