testcase

I was trying to set long long length as 64bit for 16b targets in clang and
while compiling strtoll function from newlib the following assertion append
when running llc:

llc: llvm/lib/CodeGen/SelectionDAG/LegalizeTypes.cpp:619: void
llvm::DAGTypeLegalizer::RemapValue(llvm::SDValue&): Assertion
`N.getNode()->getNodeId() != NewNode && "Mapped to new node!"' failed.

same assertion with pic16 and msp430 targets.

commands used:

llc test.ll -march=msp430
llc test.ll -march=pic16

test.ll is in attachement
