clang-p2996/llvm/test/CodeGen/AMDGPU/sdiv64.ll
Guy David f5c62ee0fa [PHIElimination] Reuse existing COPY in predecessor basic block (#131837) 
The insertion point of COPY isn't always optimal and could eventually
lead to a worse block layout, see the regression test in the first
commit.

This change affects many architectures but the amount of total
instructions in the test cases seems too be slightly lower.
