target/100784 - avoid ICE with folding __builtin_ia32_shufpd

This avoids ICEing when there is no LHS on the call by following
what foldings of other builtins do in , namely not folding.

PR target/100784
* config/i386/i386.cc (ix86_gimple_fold_builtin): Check for
LHS before folding __builtin_ia32_shufpd and friends.
