tree-optimization/112618 - unused .MASK_CALL
We have to make sure to remove unused .MASK_CALL internal function
calls after vectorization.
PR tree-optimization/112618
* tree-vect-loop.cc (vect_transform_loop_stmt): For not
relevant and unused .MASK_CALL make sure we remove the
scalar stmt.
* gcc.dg/pr112618.c: New testcase.
