Jakub Kuderski bea19a9493 [Dominators] Add DomTreeUpdater constructor from DT* and PDT*
Summary:
Previously, if a function accepts an optional DT pointer,
```
void Foo (.., DominatorTree * DT = nullptr) {
  ...
  if(DT)
    DomTreeUpdater(*DT, ...).insertEdge(A, B);
  if(DT){
    DomTreeUpdater DTU(*DT, ...);
    ... // Construct the update vector and applyUpdates
  }
  ...
  if(DT){
    DomTreeUpdater DTU(*DT, ...);
    ... // Construct the update vector and applyUpdates
  }
}
```
After this patch, it can be simplified as
```
void Foo (.., DominatorTree * DT = nullptr) {
  DomTreeUpdater DTU(DT, ...);
  ...
  DTU.insertEdge(A, B);
  if(DT){
    ... // Construct the update vector and applyUpdates
  }
  ...
  if(DT){
    ... // Construct the update vector and applyUpdates
  }
}
```

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
