Detailed Description

Pattern to canonicalize trivial vector.transfer_read operations on subviews.

This pattern eliminates unnecessary memref.subview operations when the transfer_read accesses the subview with all-zero indices. It transforms:

INPUT: subview = memref.subview memref [offset0, offset1, ...] result = vector.transfer_read subview[0, 0, ...]

OUTPUT: result = vector.transfer_read memref[offset0, offset1, ...]

The pattern only matches when:

• The base of transfer_read is defined by a memref.subview operation
• All indices in the transfer_read are constant zeros
