[PATCH] Fix (?) load_kills_store

[Zdenek Dvorak]

Hello,

considering description of load_kills_store, it seems to me that
arguments to true_dependence are passed in reversed order, which
could cause problems when one of the mems is unchanging (actually
switching the order seems to fix a misscompilation with my dce of
mems patch).

Zdenek

Changelog:
	* gcse.c (load_kills_store): Pass arguments to true_dependence
	in correct order.
