Douglas Gregor d062bff7ee Introduce a new clang-cc option
-remap-file=from;to

which takes the file "from" and transparently replaces its contents
with the contents of the file "to" from the source manager's
perspective. This is the moral equivalent of

  cp from saved
  cp to from
  <call clang>
  cp saved from
  rm saved

without all of the pesky file copying.

John McCall d28ae27d8d Push overloaded function templates through the parser using a totally different
leaked data structure than before.  This kills off the last remaining 
explicit uses of OverloadedFunctionDecl in Sema.

Mike Stump 33270211a0 More exception handling improvements... WIP.
Highlights include:

  Add a helper to generate __cxa_free_exception and _ZSt9terminatev.
  Add a region to handle EH object deallocation for ctor failures for throw.
  Add a terminate handler for __cxa_end_catch.
  A framework for adding cleanup actions for the exceptional edges only.

Douglas Gregor 53ad6b94b0 Extend the source manager with the ability to override the contents of
files with the contents of an arbitrary memory buffer. Use this new
functionality to drastically clean up the way in which we handle file
truncation for code-completion: all of the truncation/completion logic
is now encapsulated in the preprocessor where it belongs
(<rdar://problem/7434737>).

Zhongxing Xu af35329f71 Hard bifurcate the state into nil receiver and non-nil receiver, so that
we don't need to use the DoneEvaluation hack when check for 
ObjCMessageExpr.

PreVisitObjCMessageExpr() only checks for undefined receiver or arguments.

Add checker interface EvalNilReceiver(). This is a 'once-and-done' interface.

John McCall cd4b47747b Stop trying to analyze class-hierarchies for dependently-scoped id-expressions;
there's nothing interesting we can say now that we're correctly not requiring
the qualifier to name a known base class in dependent contexts.

Require scope specifiers on member access expressions to name complete types
if they're not dependent;  delay lookup when they are dependent.

Use more appropriate diagnostics when qualified implicit member access
expressions find declarations from unrelated classes.

Daniel Dunbar 55a17b66cd Add ASTUnit::LoadFromCommandLine, which creates an ASTUnit out of a list of
(clang/driver) command line arguments (including the source file).
 - The arguments are expected to include the source file.

 - The idea is that even though this is a somewhat odd API, its the form which
   many tools can most easily use (for example, by interposing with the compiler).

Also, switch index-test's -ast-from-source to use this entry point, and provide
a -arg command line argument which can be used to test that the command line
arguments are handled correctly.

Daniel Dunbar 465f4c4867 In SourceManager::isBeforeInTranslationUnit, if we are trying to compare two source locations with no common ancestor in the include stack, determine order by assuming memory buffers preceed files, and then that FileIDs are created in order.
The later assumption is patently false, but this was already broken -- this situation is conceptually impossible, my feeling is we should fix SourceManager and friends to make it impossible in practice as well. However, we need to fix PR5662 and perhaps some other things involving memory buffers first. In the short term I'm pretty sure this is reliable.

Chris, Argiris, is this going to break anything that wasn't already broken?

Evan Cheng 732351f732 Fix PR5391: support early clobber physical register def tied with a use (ewwww)
- A valno should be set HasRedefByEC if there is an early clobber def in the middle of its live ranges. It should not be set if the def of the valno is defined by an early clobber.
- If a physical register def is tied to an use and it's an early clobber, it just means the HasRedefByEC is set since it's still one continuous live range.
- Add a couple of missing checks for HasRedefByEC in the coalescer. In general, it should not coalesce a vr with a physical register if the physical register has a early clobber def somewhere. This is overly conservative but that's the price for using such a nasty inline asm "feature".

John McCall 2d74de9632 Rework how we support C++ implicit member accesses. If we can resolve an
implicit member access to a specific declaration, go ahead and create
it as a DeclRefExpr or a MemberExpr (with implicit CXXThisExpr base) as
appropriate.  Otherwise, create an UnresolvedMemberExpr or
DependentScopeMemberExpr with a null base expression.

By representing implicit accesses directly in the AST, we get the ability
to correctly delay the decision about whether it's actually an instance
member access or not until resolution is complete.  This permits us
to correctly avoid diagnosing the 'problem' of 'MyType::foo()'
where the relationship to the type isn't really known until instantiation.
