* expmed.c (struct init_expmed_rtl): Split ...
(init_expmed_one_mode): ... out of ...
(init_expmed): ... here. Initialize integer vector modes also.
(synth_mult): Handle integer vector modes.
(choose_mult_variant): Likewise.
(expand_mult_const): Likewise.
(expand_mult): Likewise.
* machmode.h (GET_MODE_UNIT_BITSIZE): New.

* config/i386/i386.c (ix86_rtx_costs): Handle CONST_VECTOR, and
integral vector modes.
