Subject: [i386] : Add -march=k8 to some testcases

Hello!

Some assembler scan tests are valid only for older ISAs; newer ISAs
generate different instruction sequences. See i.e. [1].

2011-02-10  Uros Bizjak  <ubizjak@gmail.com>

	* gcc.target/i386/parity-1.c: Use -march=k8.
	* gcc.target/i386/parity-2.c: Ditto.
	* gcc.target/i386/vecinit-1.c: Ditto.
	* gcc.target/i386/vecinit-2.c: Ditto.

Tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline SVN.
