  Log Message:
  -----------
  [ObjC][ARC] Check whether the return and parameter types of the old and
new functions are compatible before upgrading a function call to an
intrinsic call.

Sometimes users insert calls to ARC runtime functions that are not
compatible with the corresponding intrinsic functions (for example,
'i8* @objc_storeStrong' instead of 'void @objc_storeStrong'). Don't
upgrade those calls.
