[PATCH] D152556: [FuncSpec] Promote stack values before specialization

[Manolis Tsamis via Phabricator via llvm-commits]

mtsamis added a comment.

Some additional context for this change:

This is part of improving function specialization in exchange2, as initiated by  https://reviews.llvm.org/D106426.
Without this change getting the critical digits_2 function to specialize requires force-specialization=true which is undesired.

In general, this helps uncover more specialization opportunities in Fortran code and results in more consistent specialization behaviour when funcspec-max-iters > 1.
