This adds some new call operations to handle various parts of the reductions. cmat_reduce: is the initial toplevel operation from SPIR-V this is used after lowering for row/col operation on single hw supported matrix sizes. The spir-v operation is lowered into multiple of these on flex dimensions, but also can be lowered into others. cmat_reduce_finish: after multiple reduction operations on a flexible dimension matrix, there is often subsequent operations on the output matrices to finish the operation. cmat_reduce_2x2: this takes 4 input matrices, and 1 dst to do a 2x2 reduction op.
