  Changed paths:
    M llvm/lib/CodeGen/CalcSpillWeights.cpp

  Log Message:
  -----------
  [CalcSpillWeights] don't mark live intervals with spillable inlineasm ops as having infinite spill weight (#70747)

This is necessary for RegAllocGreedy support for memory folding inline
asm that uses "rm" constraints.

Thanks to @qcolombet for the suggestion.
