As said in the PR comment 7, chrec_convert and niter estimation fail
when build_nonstandard_integer_type is used in Graphite as they call
unsigned_type_for and signed_type_for that return NULL on non standard
types as returned by build_nonstandard_integer_type.

I think that unsigned_type_for and signed_type_for could be
implemented to be a bit more middle-end friendly by returning
build_nonstandard_integer_type instead of returning NULL_TREE.
