Thanks everyone for review! https://reviews.llvm.org/D42805 has landed (refactoring utils/update* scripts so that this new script can re-use the CHECK line parsing and adding functionality).
should we push forward this one?

`c-index-test` is awesome. Different name mangling is now supported:

  // NOTE: Assertions have been autogenerated by utils/update_cc_test_checks.py
  // RUN: %clang -emit-llvm -S -Os -DXX %s -o - | FileCheck %s
  // RUN: %clang -emit-llvm -S -Os %s -o - | FileCheck %s
  struct A {};
  struct B {};
  
  using T =
  #ifdef XX
  A
  #else
  B
  #endif
  ;
  
  // CHECK-LABEL: _Z3foo1A:
  // CHECK:       entry:
  // CHECK-NEXT:    ret void
  // CHECK-LABEL: _Z3foo1B:
  // CHECK:       entry:
  // CHECK-NEXT:    ret void
  T foo(T x) {
    return x;
  }

OT: It seems I can use `arc diff refactor-update_test_checks` to make this revision dependent on another git branch (`refactor-update_test_checks`).
