[PATCH, rs6000] fold-vec testcase fix-ups

[Will Schmidt <will_schmidt@vnet.ibm.com>]

Hi, 
A testcase coverage issue and an obvious typo fix.

Mostly obvious,..  OK for trunk? 
Thanks,

	* gcc.target/powerpc/fold-vec-msum-short.c: Fix typo.
	* gcc.target/powerpc/fold-vec/pack-longlong.c: Mark for 64-bit only.
