This makes the statepoint methods in IRBuilder accept a FunctionCallee, which carries both the callee and function type. This is used to add the elementtype attribute to the statepoint call. RS4GC requires an additional tweak to actually preserve that attribute -- previously the attributes on the call were completely overwritten. Differential Revision: https://reviews.llvm.org/D118886
