llvm/test/Transforms/SampleProfile/csspgo-import-list.ll fails in -DLLVM_ENABLE_EXPENSIVE_CHECKS=on builds #97108

The test fails in -DLLVM_ENABLE_EXPENSIVE_CHECKS=on -DLLVM_ENABLE_ASSERTIONS=on builds, both Debug and Release.

At llvm/lib/Transforms/IPO/SampleProfile.cpp:1420, the initialized NewCandidate may have a null CalleeSamples, leading to assert(LCS && RCS && "Expect non-null FunctionSamples"); failure in (anonymous namespace)::CandidateComparer::operator()
