Detailed Description

Match and rewrite for the pattern:

%alloc = ...
[optional] %view = memref.view %alloc ...
%subView = subview %allocOrView ...
[optional] linalg.fill(%allocOrView, %cst) ...
...
memref.copy(%in, %subView) ...
vector.transfer_read %allocOrView[...], %cst ...

into

[unchanged] %alloc = ...
[unchanged] [optional] %view = memref.view %alloc ...
[unchanged] [unchanged] %subView = subview %allocOrView ...
...
vector.transfer_read %in[...], %cst ...

Where there is no interleaved use between memref.copy and transfer_read as well as no interleaved use between linalg.fill and memref.copy (if linalg.fill is specified). This is a custom rewrite to forward partial reads (with optional fills) to vector.transfer_read.
