[CodeGen] Strip Coroutine suffixes when generating pseudo probe (#173834)
CoroSplit pass now creates separate DWARF symbols with the `.resume`, `.destroy`, `.cleanup` suffixes. https://github.com/llvm/llvm-project/pull/141889 But pseudo probes are created in an earlier pass (`SampleProfileProbePass`) before the CoroSplit, which creates a mismatch of Function GUIDs between the original function name and the function names with the coroutine suffixes during the CodeGen when the AsmPrinter iterates through the `InlinedAt` chain and generates the `InlineStack`. This will create mismatched pseudo probes in the final binary and llvm-profgen will also fail when parsing the pseudo probe section. This fix simply strips the coroutine suffixes from the inline callers' name, so the CoroSplit changes will be transparent.
