PR c++/93173 - incorrect tree sharing.
My patch for 93033 wasn't sufficient to handle all the possible sharing
introduced by split_nonconstant_init, and it occurred to me that it would
make sense to use the same unsharing technique as unshare_body, namely
copy_if_shared.
PR c++/93033
gcc/
* gimplify.c (copy_if_shared): No longer static.
* gimplify.h: Declare it.
gcc/cp/
* cp-gimplify.c (cp_gimplify_init_expr, cp_gimplify_expr): Use
copy_if_shared after cp_genericize_tree.
* typeck2.c (split_nonconstant_init): Don't unshare here.
