James Price 6176c85be8 tint: Preserve padding in matrices with three rows 
The PreservePadding transform now decomposes writes to matrices with
three rows into separate column vector writes, to avoid modifying
padding between columns.

Ben Clayton 1a1b5278d5 tint/transform: Inline HLSL uniform / storage buffers 
Change the DecomposeMemoryAccess to behave more like the DirectVariableAccess transform, in that it'll inline the access of buffer variable into the load / store helper functions, instead of passing the array down.

This avoids large array copies observed with FXC, which can have *severe* performance costs.
