use rand instead of random

rand is in ISO C, whereas random is only in POSIX, so it makes sense
to use the more portable function everywhere instead of falling back
from one to the other on systems that miss the less portable one.

for  gcc/testsuite/ChangeLog

	* gcc.target/i386/sse2-mul-1.c: Use rand.  Drop fallback.
	* gcc.target/i386/sse4_1-blendps-2.c: Likewise.
	* gcc.target/i386/sse4_1-blendps.c: Likewise.
	* gcc.target/i386/xop-vshift-1.c: Likewise.
	* gcc.target/powerpc/direct-move.h: Likewise.
