Do you have any test for the fix?



================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUTargetTransformInfo.cpp:1192
   if (AllocaSize)
-    return ArgAllocaCost;
+    return ArgAllocaCost * getInliningThresholdMultiplier();
   return 0;

Nit: It seems instead of this modification you can just swap two lines
```
1582:  Threshold *= TTI.getInliningThresholdMultiplier();
1583:  Threshold += TTI.adjustInliningThreshold(&Call);

```
[[ https://reviews.llvm.org/source/llvm-github/browse/main/llvm/lib/Analysis/InlineCost.cpp$1582-1583 | in InlineCost.cpp ]] so we'll stay with just one place of `* getInliningThresholdMultiplier()`.
