[PATCH] D113900: [PowerPC] Prevent the optimizer from producing wide vector types in IR.

[Lei Huang via Phabricator via llvm-commits]

lei added a comment.

Instead of adding:

  if (isMMAType(Src))
      return InstructionCost::getMax();

to all the different cost calculating functions, is it possible to just add them the underlying functions?

For example I see this check was added multiple functions that also calls `vectorCostAdjustment()` or `getMemoryOpCost()`.  
I haven't tried this so not sure if it will work, but was thinking it would make sense to at least add this to `vectorCostAdjustment()` 
since it's a vector type.
