If it does, it doesn't advertize them:
make mddump
grep '"v\?ashlv[0-9qhsdi]*3"' tmp-mddump.md
(define_expand ("vashlv8qi3")
(define_expand ("vashlv16qi3")
(define_expand ("vashlv4hi3")
(define_expand ("vashlv8hi3")
(define_expand ("vashlv2si3")
(define_expand ("vashlv4si3")
Ditto for ashr and lshr instead of ashl.
