In general there is no way to get to the ASTContext from most AST nodes
(Decls are one of the exception). This will be a problem when implementing
the rest of APValue::dump since we need the ASTContext to dump some kinds of
APValues.
The ASTContext* in ASTDumper and TextNodeDumper is not always non-null.
This is because we still want to be able to use the various dump() functions
in a debugger.
No functional changes intended.
Reverted in fcf4d5e4499a391dff42ea1a096f146db44147b6 since a few dump()
functions in lldb where missed.

Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across the monorepo.

This adds the -ast-dump=json cc1 flag (in addition to -ast-dump=default, which is the default if no dump format is specified), as well as some initial AST dumping functionality and tests.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary: Its job is covered by -ast-dump. The option is rarely used and lacks many AST nodes which will lead to llvm_unreachable() crash.

The existing conditions are not consistent. Some have braces and define a temporary Decl while others simply call `<< *cast<XXXDecl>(I)` (mostly the NamedDecl overload of operator<<).
Just use the latter for consistency and brevity.
llvm-svn: 343072
For example, given:
#define bool _Bool
_Bool i;
void fn() { 1; }
-ast-print produced:
tmp.c:3:13: warning: expression result unused
void fn() { 1; }
^
bool i;
void fn() {
1;
}
That fails to compile because bool is undefined.
Details:
Diagnostics print _Bool as bool when the latter is defined as the
former. However, diagnostics were altering the printing policy for
-ast-print as well. The printed source was then invalid because the
preprocessor eats the bool definition.
Problematic diagnostics included suppressed warnings (e.g., add
-Wno-unused-value to the above example), including those that are
suppressed by default.
This patch fixes this bug and cleans up some related comments.

Summary:
`ASTPrinter` allows setting the ouput to any O-Stream, but that printer creates source-code-like syntax (and is also marked with a `FIXME`). The nice, colourful, mostly human-readable `ASTDumper` only works on the standard output, which is not feasible in case a user wants to see the AST of a file through a code navigation/comprehension tool.
This small addition of an overload solves generating a nice colourful AST block for the users of a tool I'm working on, [[ http://github.com/Ericsson/CodeCompass | CodeCompass ]], as opposed to having to duplicate the behaviour of definitions that only exist in the anonymous namespace of implementation TUs related to this module.

This changes the CompilerInstance::createOutputFile function to return
a std::unique_ptr<llvm::raw_ostream>, rather than an llvm::raw_ostream
implicitly owned by the CompilerInstance. This in most cases required that
I move ownership of the output stream to the relevant ASTConsumer.
The motivation for this change is to allow BackendConsumer to be a client
of interfaces such as D20268 which take ownership of the output stream.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.
I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.
