I don't know if what you're trying to do is legal. You're taking a bitcode file
compiled for x86_64 and trying to output x86. It can't handle the i64 type in a
register, so it's trying to "expand" it into multiple integers.

Simplified version:

target triple = "x86_64-unknown-linux-gnu"

define void @autogen_5860_500() {
BB:
  %Shuff = shufflevector <8 x i64> zeroinitializer, <8 x i64> zeroinitializer,
<8 x i32> <i32 undef, i32 7, i32 undef, i32 11, i32 13, i32 undef, i32 1, i32
3>
  %B = xor <8 x i64> %Shuff, zeroinitializer
  br label %CF

CF:                                               ; preds = %CF, %BB
  %S17 = icmp uge <8 x i64> %B, zeroinitializer
  br i1 undef, label %CF, label %CF39.critedge

CF39.critedge:                                    ; preds = %CF
  %Shuff31.c = shufflevector <8 x i1> %S17, <8 x i1> %S17, <8 x i32> <i32
undef, i32 7, i32 9, i32 11, i32 13, i32 15, i32 1, i32 3>
  ret void
}
