[05/11] Add a vect_stmt_to_vectorize helper function
This patch adds a helper that does the opposite of vect_orig_stmt:
go from the original scalar statement to the statement that should
actually be vectorised.
The use in the last two hunks of vectorizable_reduction are because
reduc_stmt_info (first hunk) and stmt_info (second hunk) are already
pattern statements if appropriate.
