Yes, this really occurred in the wild (while building wine)!  In the original
code the i160 appears as padding at the end of a struct.

$ cat bigint.ll 
target datalayout =
"e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:64-f32:32:32-f64:32:64-v64:64:64-v128:128:128-a0:0:64-f80:32:32-f128:128:128-n8:16:32"
target triple = "i386-unknown-linux-gnu"

@g = global i160 zeroinitializer

$ llc bigint.ll 
llc: llvm/lib/CodeGen/AsmPrinter/AsmPrinter.cpp:1633: void
EmitGlobalConstantLargeInt(const llvm::ConstantInt*, unsigned int,
llvm::AsmPrinter&): Assertion `(BitWidth & 63) == 0 && "only support multiples
