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.c (ix86_gimple_fold_builtin): Check for
LHS before folding __builtin_ia32_shufpd and friends.

(cherry picked from commit d63d9c3dd160dce24f0209f193b8e7388b19f712)
