Linker: Avoid scheduling the link of a global value twice due to an alias

3d4f3a0da90bd1a3 (https://reviews.llvm.org/D20586) avoided rescheduling
a global value that was materialized first through a regular value, and
then again through an alias. This commit catches the dual, avoiding
rescheduling when the global value is first materialized through an
alias.
