…#16533) Summary: Add a new pass - DecomposeBatchNorm - which converts standalone (non-fused) batch norm operators to 1x1 depthwise convolution. This prevents delegation graph breaks when batch norm operators can't be fused. Differential Revision: D90422630

Updated to add test coverage around dtype, affine=False, memory_format/dim_order, and more comprehensive checks on the conv node created by the pass. Will re-open and request review once CI finshes. |
