  [llvm] Avoid out-of-order evaluation in DebugInfo (#125116)

This is an upstream proposal from
https://github.com/intel/intel-graphics-compiler/commit/e60884cb98c4332a0eecff8396eb353c5b86cd35
We observed malfunctioning StripNonLineTableDebugInfo during debugging
and it's caused by out-of-order evaluation, this is a C++ level semantic
ambiguity issue, refer
https://en.cppreference.com/w/cpp/language/eval_order
Solution is simply separating one line into two.
