gimplify: Gimplify value in gimplify_init_ctor_eval_range [PR98353]

Browse Source 
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).

2020-12-21  Jakub Jelinek  <jakub@redhat.com>

	PR c++/98353
	* gimplify.c (gimplify_init_ctor_eval_range): Gimplify value before
	storing it into cref.

	* g++.dg/opt/pr98353.C: New test.
