    A llvm/test/Transforms/LowerMatrixIntrinsics/shape-verification.ll

  Log Message:
  -----------
  [Matrix] Add shape verification.

At the moment, lower-matrix-intrinsics accepts mis-matches between
shapes for operations. See shape-verification.ll for an example where
@llvm.matrix.column.major.load specifies 6x1 and then the use
(@llvm.matrix.multiply) specifies the operand to have 1x6.

This patch adds verification for shapes to check if shapes match.
