[Patch] src/if_cscope.c: Add search type 9 (find assignments to) introduced in cscope 15.8

[UliM]

Hi,

there is a new search type in cscope 15.8 to search for assignments
and this patch allows you to use it from vim.
The same functionality had been offered before by a RedHat patch.
However, that patch reused search type 4 (text) and therefore didn't
require changes to vim.
See the cscope Changelog, specifically the entry for 2012-03-05.

Thanks,

Uli
