Make more use of int_mode_for_mode
This patch converts more places that could use int_mode_for_mode
instead of mode_for_size. This is in preparation for an upcoming
patch that makes mode_for_size itself return an opt_mode.
The reason for using required () in exp2_immediate_p is that
we go on to do:
trunc_int_for_mode (..., int_mode)
which would be invalid for (and have failed for) BLKmode.
The reason for using required () in spu_convert_move and
resolve_simple_move is that we go on to use registers of
the returned mode in non-call rtl instructions, which would
be invalid for BLKmode.

gcc/
* config/spu/spu.c (exp2_immediate_p): Use int_mode_for_mode.
(spu_convert_move): Likewise.
* lower-subreg.c (resolve_simple_move): Likewise.
