[PATCH][committed] Fix couple of typos and outdated function reference in comment

[Kyrill Tkachov <kyrylo dot tkachov at arm dot com>]

Hi all,

I've committed the attached patch to the introductory comment in haifa-sched.c 
as obvious with r209184.
The function compute_block_backward_dependences was renamed to 
compute_block_dependences in 2007but the comment was not updated.

    * haifa-sched.c: Fix outdated function reference and minor
    grammar errors in introductory comment.
