This is new, we were not checking for non standard allocdiagonal, not along the last dims!

This PR provides a POC for#1455
owner_opandowner_op_and_inputs.if x.owner.op is not None and isinstance(x.owner.op, ...)in favor ofisinstance(x.owner_op, ...)casestatement. This makes nested patterns easier to write. Eg.case (Blocwise(Dot()), a, b)for a singlematch x.owner_op_and_inputs.match_argsso common parametrized Ops (Elemwise, Blockwise) and Constants are easier to pattern match without kwargsis_matrix_transposeandis_left_expanded_matrix_transposeproperty to DimShuffle, for easier pattern matchingI then refactored the existing linalg rewrites as a POC. I went a bit overboard and tried to standardize names, and fuse rewrites that were pretty simple to combine.
CC@tanish1729 who did many of these rewrites, see if it feels nicer?
