Preprocessed test case.

Compiling the attached test case with the attached command line produces the
following assertion failure when running clang built from trunk (15 Feb 2017):

clang-4.0: /work/sources/llvm/current/lib/Target/X86/X86RegisterInfo.cpp:735:
virtual void
llvm::X86RegisterInfo::eliminateFrameIndex(llvm::MachineBasicBlock::iterator,
int, unsigned int, llvm::RegScavenger*) const: Assertion `(!Is64Bit ||
isInt<32>((long long)FIOffset + Imm)) && "Requesting 64-bit offset in 32-bit
immediate!"' failed.

The stack backtrace looks like this:
