778b6a21 - [DirectX] Allow vector Allocas to be transformed into arrays (#145972)

[DirectX] Allow vector Allocas to be transformed into arrays (#145972) fixes #145782 This change modifies `isArrayOfVectors` into `isVectorOrArrayOfVectors`. The previous implementation did not support vector to array transformations. Further it was too simplistic and didn't assume allocas would create multidimensional arrays.
