           Summary: [AVX] JIT fails for insertelement operations ("Unknown
                    immediate size" / "Wrong MachineOperand accessor")

Two test functions the JIT fails to compile

The JIT fails to compile the two attached test functions under Linux x86-64
with AVX enabled (LLVM svn trunk).
llc on the other hand works fine:
llc jittest.ll -mcpu=corei7-avx -mattr+avx -o jittest.s


The code that instantiates the execution engine looks like this:

InitializeNativeTarget();
EngineBuilder eb = EngineBuilder(mod);
eb.setEngineKind(EngineKind::JIT);
eb.setErrorStr(&errorMessage);
eb.setJITMemoryManager(JITMemoryManager::CreateDefaultMemManager());
eb.setOptLevel(CodeGenOpt::Aggressive);
eb.setAllocateGVsWithCode(false);
eb.setCodeModel(CodeModel::Default);
eb.setMCPU("corei7-avx");
std::vector<std::string> attrs;
attrs.push_back("avx");
eb.setMAttrs(attrs);

Here is the output of gdb for function 'test':
