Do not warn when ignoring the return value of _cairo_rectangle_intersect()
gcc complains that
cairo-surface-wrapper.c:647: warning: ignoring return value of
‘_cairo_rectangle_intersect’, declared with attribute warn_unused_result
It can be silenced by making _cairo_rectangle_intersect()
cairo_private_no_warn. This makes it possible to avoid unused
temporary variables in other places and reduces the dead assignments
reported by clang static analyzer from 114 to 98.
