[PATCH] D37005: Add include/clang/Tooling/ASTDiff/ASTPatch.h

[Johannes Altmanninger via Phabricator via cfe-commits]

This adds a functions to remove AST nodes.
It works for Decl, and for Stmt nodes that are children of a
CompoundStmt.

Sometimes it is not possible to remove a Decl from its context
despite DeclContext.containsDecl() returning true. Instead the program
crashes. An example for this is in the tests. So this might be a
bug although it may never occur under normal circumstances.
