clang-p2996/llvm/test/CodeGen/AMDGPU/insert-singleuse-vdst.mir
Scott Egerton 4a305d40a3 [AMDGPU] Exclude certain opcodes from being marked as single use (#91802) 
The s_singleuse_vdst instruction is used to mark regions of instructions
that produce values that have only one use.
Certain instructions take more than one cycle to execute, resulting in
regions being incorrectly marked.
This patch excludes these multi-cycle instructions from being marked as
either producing single use values or consuming single use values
or both depending on the instruction.
