Restore STMT_VINFO_VECTYPE during analysis, set to NULL for all stmts
The following makes vect_analyze_stmt call vectorizable_* with all
STMT_VINFO_VECTYPE NULL_TREE but restores the value for eventual
iteration with single-lane SLP. It clears it for every stmt during
vect_transform_stmt.
* tree-vect-stmts.cc (vect_transform_stmt): Clear
STMT_VINFO_VECTYPE for all stmts.
(vect_analyze_stmt): Likewise. But restore at the end again.
