Re: [C++ PATCH] Emit array initialization from ctor as loop if possible (PR c++/59659)

[Jason Merrill]

I'm inclined to handle this situation by using a RANGE_EXPR in 
process_init_constructor_array, and then handling that appropriately in 
build_vec_init, so that we don't have to build up the huge CONSTRUCTOR. 
 Would you like to do that, or shall I take it over?
