This follows on from similar changes a couple of months ago and
is needed when general modes have variable size.

Tested on aarch64-linux-gnu, x86_64-linux-gnu and powerpc64le-linux-gnu.
Applied as obvious.

gcc/
	* tree-vect-loop.c (vect_create_epilog_for_reduction): Use
	SCALAR_TYPE_MODE instead of TYPE_MODE.
