Hi!
Sorry this is all taking so long.

"early" should indent together wit

Hi
Enable GIMPLE folding of the vec_splat() intrinsic. (v3).
This uses the tree_vec_extract() function out of tree-vect-generic.c
to retrieve the splat value, which is a BIT_FIELD_REF. That function is
made non-static as part of this change.
Testcases are already in-tree.
V2 update
