  Log Message:
  -----------
  [mlir][Transforms][NFC] Dialect conversion: Cache `UnresolvedMaterializationRewrite`

The dialect conversion already maintains a set of unresolved materializations (`UnrealizedConversionCastOp`). Turn that set into a map that maps from ops to `UnresolvedMaterializationRewrite *`. This improves efficiency a bit, because an iteration over `ConversionPatternRewriterImpl::rewrites` can be avoided.

Also delete some dead code.
