  Log Message:
  -----------
  [Matrix] Add option to use row-major matrix layout as default.

This patch adds a -matrix-default-layout option which can be used to
set the default matrix layout to row-major or column-major (default).

The initial patch updates codegen for loads, stores, binary operators
and matrix multiply.
