[CMake] lli depends on intrinsics_gen

[CMake] lli depends on intrinsics_gen

ChildTarget.cpp has the following include chain:

llvm/ExecutionEngine/Orc/OrcABISupport.h
llvm/ExecutionEngine/Orc/IndirectionUtils.h
llvm/IR/IRBuilder.h
llvm/IR/ConstantFolder.h
llvm/IR/InstrTypes.h
llvm/IR/Attributes.h
llvm/IR/Attributes.gen

This means lli needs to depend on intrinsics_gen.
