Do NOT inline self recursive calls into other functions. This is causing the
pool allocator no end of trouble, and doesn't make a lot of sense anyway. This does not solve the problem with mutually recursive functions, but they are much less common. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9828 91177308-0d34-0410-b5e6-96231b3b80d8
