[PATCH] ira: Remove duplicate `memset' over `full_costs' from `assign_hard_reg'

["Maciej W. Rozycki" <macro@embecosm.com>]

Remove duplicate clearing of `full_costs' made in `assign_hard_reg', 
which has been there since the beginning, i.e. commit 058e97ecf33a
("IRA has been merged into trunk"), 
<https://gcc.gnu.org/ml/gcc-patches/2008-08/msg01932.html>.

	gcc/
	* ira-color.cc (assign_hard_reg): Remove duplicate `memset' over 
	`full_costs'.
