Reverts llvm/llvm-project#194501 as this is triggering an assert in CI:
```
Assertion failed: ((!HasTemplateParamsInName || Tag != dwarf::DW_TAG_subprogram) && "subprogram with template-like name should have a linkage name"), function getChildDeclContext, file DWARFLinkerDeclContext.cpp, line 114.
```
