[LLVMdev] Remove function from module

[Михаил]

Thanks, but I replaceAllUsesWith() - works well, but I still get bug in eraseFromParent():

	While deleting: i32 (%class.B*, i32)* %_ZN1B1xEi
	An asserting value handle still pointed to this value!
	UNREACHABLE executed at /Users/neonomaly/LLVM/LLVM/lib/VMCore/Value.cpp:561!


Yours sincerely,
Kadysev Mikhail
