Architecture specific code should reside in architecture specific directory
not in Atom. Looks like there are no efforts being made at this moment to
support ARM, so let's remove it for now.

Don't suggest putting 'operator new' or 'operator delete' in a namespace to fix a two-phase lookup issue. That's not permitted.

Introduce CXXStdInitializerListExpr node, representing the implicit
construction of a std::initializer_list<T> object from its underlying array.
The AST representation of such an expression goes from an InitListExpr with a
flag set, to a CXXStdInitializerListExpr containing a MaterializeTemporaryExpr
containing an InitListExpr (possibly wrapped in a CXXBindTemporaryExpr).

This more detailed representation has several advantages, the most important of
which is that the new MaterializeTemporaryExpr allows us to directly model
lifetime extension of the underlying temporary array. Using that, this patch
*drastically* simplifies the IR generation of this construct, provides IR
generation support for nested global initializer_list objects, fixes several
bugs where the destructors for the underlying array would accidentally not get
invoked, and provides constant expression evaluation support for
std::initializer_list objects.

entire definition, which is excessively verbose in this context.

the beginning of a header refer to the same macro name.  Includes a fix-it

were lacking ExprWithCleanups nodes in some cases where the new approach to
lifetime extension needed them).

Original commit message:

Rework IR emission for lifetime-extended temporaries. Instead of trying to walk
into the expression and dig out a single lifetime-extended entity and manually
pull its cleanup outside the expression, instead keep a list of the cleanups
which we'll need to emit when we get to the end of the full-expression. Also
emit those cleanups early, as EH-only cleanups, to cover the case that the
full-expression does not terminate normally. This allows IR generation to
properly model temporary lifetime when multiple temporaries are extended by the
same declaration.

We have a pre-existing bug where an exception thrown from a temporary's
destructor does not clean up lifetime-extended temporaries created in the same
expression and extended to automatic storage duration; that is not fixed by
this patch.

I'm taking David Blaikie's suggestion to use an
Optional<PPC::Predicate> return value instead.  That's the right
solution for this problem.  Thanks for pointing out that possibility!

Moving RewriteContainer's constructor impl to Transform.cpp to reduce clutter.
More things will soon be added to this header.

llvm-svn: 183856

Next step toward supporting migrating headers. Instead of using ClangTool's
ability to override all files at once, use a custom FrontendAction and override
only the source (and eventually headers) the action is about to parse.

Use of newFrontendActionFactory() is replaced with a new factory maker provided
by Transform.

Introducing PRED_BAD caused some unexpected warnings that are now

Summary:
Basically, don't special-case line comments in this regard. And fixed
an incorrect test, that relied on the wrong behavior.

This is a preparatory patch for fast-isel support.  The instruction
selector will need to access some functions in PPCGenCallingConv.inc,
which in turn requires several helper functions to be defined.  These
are currently defined near the only use of PCCGenCallingConv.inc,
inside PPCISelLowering.cpp.  This patch moves the declaration of the
functions into the associated header file to provide the needed
visibility.

No functional change intended.
