[RFA/testsuite] Update gcc.dg/vshift-*.c tests to use rand and not random

[Matthew Gretton-Dann]

All,

[Apologies to those getting this twice - used wrong account to send it 
initially].

The attached patch updates the gcc.dg/vshift-*.c tests to call the 
function rand and not random, as random is not available on all targets, 
but rand should be as it is in the Standard C Library.

Can someone please review the patch?

Thanks,

Matt
