f4ccd11075 Replace OwningPtr<T> with std::unique_ptr<T>.
This compiles with no changes to clang/lld/lldb with MSVC and includes
overloads to various functions which are used by those projects and llvm
which have OwningPtr's as parameters. This should allow out of tree
projects some time to move. There are also no changes to libs/Target,
which should help out of tree targets have time to move, if necessary.

ac69459e0f Replace the F_Binary flag with a F_Text one.
After this I will set the default back to F_None. The advantage is that
before this patch forgetting to set F_Binary would corrupt a file on windows.
Forgetting to set F_Text produces one that cannot be read in notepad, which
is a better failure mode :-)

0a3368cde5 [TableGen] Correctly generate implicit anonymous prototype defs in multiclasses
Even within a multiclass, we had been generating concrete implicit anonymous
defs when parsing values (generally in value lists). This behavior was
incorrect, and led to errors when multiclass parameters were used in the
parameter list of the implicit anonymous def.

If we had some multiclass:

multiclass mc<string n> {

 ... : SomeClass<SomeOtherClass<n> >

The capture of the multiclass parameter 'n' would not work correctly, and
depending on how the implicit SomeOtherClass was used, either TableGen would
ignore something it shouldn't, or would crash.

To fix this problem, when inside a multiclass, we generate prototype anonymous
defs for implicit anonymous defs (just as we do for explicit anonymous defs).
Within the multiclass, the current record prototype is populated with a node
that is essentially: !cast<SomeOtherClass>(!strconcat(NAME, anon_value_name)).
This is then resolved to the correct concrete anonymous def, in the usual way,
when NAME is resolved during multiclass instantiation.

2370e55a53 [TableGen] Use the same anonymous name as the prefix on all multiclass defs
TableGen had been generating a different name for an anonymous multiclass's
NAME for every def in the multiclass. This had an unfortunate side effect: it
was impossible to reference one def within the multiclass from another (in the
parameter list, for example). By making sure we only generate an anonymous name
once per multiclass (which, as it turns out, requires only changing the name
parameter to reference type), we can now concatenate NAME within the multiclass
with a def name in order to generate a reference to that def.

This does not matter so much, in and of itself, but is necessary for a
follow-up commit that will fix variable capturing in implicit anonymous
multiclass defs (and that is important).

cee93e95a4 TableGen: Generate valid identifiers for anonymous records
Backends like OptParserEmitter assume that record names can be used as valid
identifiers.

The period '.' in generated anonymous names broke that assumption, causing a
build-time error and in practice forcing all records to be named.

4717fd4c0f Allow TableGen DAG arguments to be just a name.
DAG arguments can optionally be named:

  (dag node, node:$name)

With this change, the node is also optional:

  (dag node, node:$name, $name)

The missing node is treated as an UnsetInit, so the above is equivalent
to:

  (dag node, node:$name, ?:$name)

This syntax is useful in output patterns where we currently require the
types of variables to be repeated:

  def : Pat<(subc i32:$b, i32:$c), (SUBCCrr i32:$b, i32:$c)>;

This is preferable:

  def : Pat<(subc i32:$b, i32:$c), (SUBCCrr $b, $c)>;

f8ea5a5a27 Make sure TableGen exits with an error code after printing errors.
This makes it possible to report multiple errors in one invocation.
There are already calls to PrintError in CodeGenDAGPatterns.cpp which
previously would not cause TableGen to fail.

a170f520a9 tblgen: Diagnose duplicate includes.
A double inclusion will pretty much always be an error in TableGen, so
there's no point going on just to die with "def already defined" or
whatnot.

I'm not too thrilled about the "public: ... private: ..." to expose the
DependenciesMapTy, but I really didn't see a better way to keep that
type centralized. It's a smell that indicates that some refactoring is
needed to make this code more loosely coupled.

This should avoid all bugs of the same nature as PR15189.

7be9021754 Inline this into its only caller.
It's clearer and additionally this gets rid of the usage of `DefmID`,
which doesn't really correspond to anything in the language (it was just
used in the name of this parsing function which parsed a `MultiClassID`
and returned that multiclass's record).

This area of the code still needs a lot of work.

d04a8d4b33 Use the new script to sort the includes of every file under lib.
Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

61131ab15f Remove exception handling usage from tblgen.
Most places can use PrintFatalError as the unwinding mechanism was not
used for anything other than printing the error. The single exception
was CodeGenDAGPatterns.cpp, where intermediate errors during type
resolution were ignored to simplify incremental platform development.
This use is replaced by an error flag in TreePattern and bailout earlier
in various places if it is set.

63554988a9 tblgen: Use appropriate LLVM-style RTTI functions.
Use isa<> or cast<> when semantically that is what is happening. Also
some trivial "style" cleanups at fix sites.

736ceace11 tblgen: Replace uses of dynamic_cast<XXXRecTy> with dyn_cast<>.
This is a mechanical change of dynamic_cast<> to dyn_cast<>. A number of
these uses are actually more like isa<> or cast<>, and will be changed
to the semanticaly appropriate one in a future patch.

f42a6741de tblgen: Put new TableGenMain API in place.
In order to avoid rev-lock with Clang when moving to the new API, also
preserve the current API temporarily and insert a shim to implement the
new API in terms of the old.
