Optimize eliminate FP mechanism. This time optimize a function which has no call but fixed stack objects. LLVM eliminates FP on such functions now. Also, optimize GOT/PLT registers save/restore instructions if a given function doesn't uses them. In addition, remove generating mechanism of `.cfi` instructions since those are taken from other architectures and not inspected yet. Update regression tests, also.
