Decorate string_view members with nonnull attribute
The C++ committee has confirmed that passing a null pointer to the
unary basic_string_view constructor is undefined. This removes the check
from our implementation, and adds the nonnull attribute to warn when the
compiler can detect undefined input.
* include/std/string_view (basic_string_view(const CharT*)): Remove
check for null pointer and add nonnull attribute.
(compare(const CharT*), compare(size_type, size_type, const CharT*))
(find(const CharT*, size_type), rfind(const CharT*, size_type))
(find_first_of(const CharT*, size_type))
(find_last_of(const CharT*, size_type))
(find_first_not_of(const CharT*, size_type))
(find_last_not_of(const CharT*, size_type)): Add nonnull attribute.
