Remove debug spew.


This diff adds lowering of the linalg.reshape op to LLVM.

A new descriptor is created with fields initialized as follows:

1. allocatedPTr, alignedPtr and offset are copied from the source descriptor
2. sizes are copied from the static destination shape
3. strides are copied from the static strides collected with `getStridesAndOffset`

Only the static case in which the target view conforms to strided memref
semantics is supported. Other cases are left for future work and will be added on
a per-need basis.
