  Log Message:
  -----------
  Revert "Re-reapply "[DebugInfo] Use variadic debug values to salvage BinOps and GEP instrs with non-const operands""

This reverts commit 791930d74087b8ae8901172861a0fd21a211e436, as per
https://llvm.org/docs/DeveloperPolicy.html#patch-reversion-policy.

I observed breakage with the Linux kernel, as reported at
https://reviews.llvm.org/D91722#2724321

Fixes exist at
https://reviews.llvm.org/D101523
https://reviews.llvm.org/D101540

but they have not landed so to unbreak the tree for the weekend, revert
this commit.

Commit b11e4c990771 ("Revert "[DebugInfo] Drop DBG_VALUE_LISTs with an
excessive number of debug operands"") only reverted one follow-up fix,
not the original patch that broke the kernel.
