Imported functions and variables get the visibility from the prevailing module.
However, non-prevailing definitions do not get the visibility.

This patch adds visibility bits to GlobalValueSummary::GVFlags so that
non-prevailing definitions can get the constraining visibility from the
prevailing definitions.
