  Changed paths:
    M flang/lib/Optimizer/Analysis/AliasAnalysis.cpp
    A flang/test/HLFIR/opt-variable-assign-omp.fir

  Log Message:
  -----------
  [flang][AliasAnalysis] don't crash on load from blockarg (#120760)

Values can have no defining operation when the value is a blockarg. I
wrote this as a test for hlfir bufferization rather than alias analysis
because I couldn't find a way to add the test.ptr attribute to a block
argument.
