Enable -widen-vmovs by default.

This will widen 32-bit register vmov instructions to 64-bit when
possible.  The 64-bit vmovd instructions can then be translated to NEON
vorr instructions by the execution dependency fix pass.

The copies are only widened if they are marked as clobbering the whole
D-register.
