Pietro, thanks again for the patch that led up to this. This is

attached patch fixes a runtime out-of-bounds error when an iterator of an

The rtx costs logic for CONST_VECTOR, VEC_DUPLICATE and VEC_SELECT sets
the cost unconditionally to the movi, dup or extract fields of extra_cost,

This implements the missing functions in _Utf_iterator to support
reverse iteration. All existing tests pass when the view is reversed, so

* include/bits/unicode.h (_Utf_iterator::operator--):
I incorrectly assumed that all targets that support __int128 use the

supports __int128 (because it's an ILP32 target on 64-bit hardware).
Add casts to the tests so that we get the correct expected values using
size_t type.
