Use default type_for_size langhook
The gcc constant folding code uses the type_for_size langhook. Use the
default implementation instead of crashing when the langhook is
called. Add a new testcase "prims_struct_eq.rs" that creates trees
that triggers the constant folding.
Also remove the write_globals langhook which was removed when early
debug was integrated into gcc.
