Apply pattern initialization only when have_insn_for return true.
For -ftrivial-auto-var-init=pattern, initialize the variable with patterns only
when have_insn_for (SET, mode) return true. Otherwise initialize it with zeros.
with this change, _Complex long double on X86 is initialized to zero for
pattern initialization.
