With recent disturbed testing this FAIL got unnoticed. Fixed as follows
(we have a constant " " that we'd like to replicate in a vector).
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied to trunk.

* tree-vect-stmts.c (vect_get_vec_def_for_operand): Use
VIEW_CONVERT_EXPR to convert constants.
(vect_is_simple_use): Treat all constants as vec_constant_def.
