poly_int: get_mask_mode
This patch makes TARGET_GET_MASK_MODE take polynomial nunits and
vector_size arguments. The gcc_assert in default_get_mask_mode
is now handled by the exact_div call in vector_element_size.

* target.def (get_mask_mode): Take the number of units and length
as poly_uint64s rather than unsigned ints.
* targhooks.h (default_get_mask_mode): Update accordingly.
* targhooks.c (default_get_mask_mode): Likewise.
* config/i386/i386.c (ix86_get_mask_mode): Likewise.
* doc/tm.texi: Regenerate.
