Switch clang_createTranslationUnitFromSourceFile to use ASTUnit::LoadFromCommandLine.
 - This is much faster, as it avoids the overhead of dumping an AST file to disk and reloading it.
 - For debugging purposes, there is a clang_setUseExternalASTGeneration hook which can be used to disable this.

On the Sketch Cocoa app, the speedup is pretty nice, especially when using a PCH file while scanning the source:

Extend -remap-file=from;to to permit mapping from a non-existent
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.

Extend the CIndex code-completion API to perform code completion
involving unsaved files, using the -remap-file= functionality recently
added to clang-cc.

r90313, in which OverloadedFunctionDecl is removed and never spoken of again.

Fix ASTUnit::getOriginalSourceFileName() when using ASTUnit's derived from
source files.

ASTUnit: Don't create an LLVMContext, it shouldn't be needed.

Rip out the last remaining implicit use of OverloadedFunctionDecl in Sema:
LookupResult::getAsSingleDecl() is no more.  Shift Sema::LookupSingleName to
return null on overloaded results.

terminate doesn't throw.

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.

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.

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.

Fix another "operator delete missing" crash: make sure we don't check
isVirtual() before we've actually calculated whether the destructor is
virtual.

Tweak test to check for a bit more.

Make sure to call AddOverriddenMethods for implicit copy assignment operators;
it's rare, but possible, for the difference to be significant.

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>).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90300 91177308-0d34-0410-b5e6-96231b3b80d8

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.
