file. This is accomplished by introducing the notion of a "virtual"
file into the file manager, which provides a FileEntry* for a named
file whose size and modification time are known but which may not
exist on disk.

Added a cute little test that remaps both a .c file and a .h file it
includes to alternative files.

In Sema, whenever we think that a function is going to cause a vtable to be generated, we mark any virtual implicit member functions as referenced.

LookupResult::getAsSingleDecl() is no more.  Shift Sema::LookupSingleName to
return null on overloaded results.

  -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.

leaked data structure than before.  This kills off the last remaining 
explicit uses of OverloadedFunctionDecl in Sema.

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.

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>).

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.

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.
