Ted Kremenek 7716cd62b3 Modify CursorVisitor to also walks CXXOperatorCallExprs using data-recursion. Fixes <rdar://problem/8659019>.

Ted Kremenek c7a5bae597 Annotate tokens in a separate thread to avoid blowing out stack space. While the CursorVisitor
is gradually becoming more data recursive, AnnotateTokensVisitor does its own recursive call
within the visitor that can still blow out the stack.  This can potentially be reworked to avoid this,
but for now just do token annotation on a separate thread.

Ted Kremenek 92209a45b9 Generalize data-recursive visitation in CursorVisitor to also handle MemberExprs
and CXXCallMemberExprs.  This scheme is hopefully general enough to extend to the
rest of the visitor if necessary.

Douglas Gregor 44c6ee7729 Improve ASTUnit's capture of diagnostics so that the
diagnostic-capturing client lives as long as the ASTUnit itself
does. Otherwise, we can end up with crashes when we get a diagnostic
outside of parsing/code completion. The circumstances under which this
happen are really hard to reproduce, because a file needs to change
from under us.

Douglas Gregor 229bebdeb5 ntroduce clang_getSpellingLocation() into libclang, to provide the
location where we're spelling a token even within a
macro. clang_getInstantiationLocation() tells where we instantiated
the macro.

I'm still not thrilled with the CXSourceLocation/CXSourceRange APIs,
since they gloss over macro-instantiation information.

Take 2: this time, adjusted tests appropriately and used a "simple"
approach to the spelling location.

Ted Kremenek 15c1e368bb Add CursorVisitor::VisitBinaryOperator() to explicitly handle the case where we can blow out the stack due
to deeply nested BinaryOperators.  This is done by turning the explicit recursion into being data recursive.

Douglas Gregor 1ccc8416a0 Remove broken support for variadic templates, along with the various
abstractions (e.g., TemplateArgumentListBuilder) that were designed to
support variadic templates. Only a few remnants of variadic templates
remain, in the parser (parsing template type parameter packs), AST
(template type parameter pack bits and TemplateArgument::Pack), and
Sema; these are expected to be used in a future implementation of
variadic templates.

But don't get too excited about that happening now.

Argyrios Kyrtzidis 71731d6b05 Implement -working-directory.
When -working-directory is passed in command line, file paths are resolved relative to the specified directory.
This helps both when using libclang (where we can't require the user to actually change the working directory)
and to help reproduce test cases when the reproduction work comes along.

--FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains
 the working directory value if set).
--FileSystemOptions are passed around to various interfaces that perform file operations.
--Opening & reading the content of files should be done only through FileManager. This is useful in general since
 file operations will be abstracted in the future for the reproduction mechanism.

FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same
FileManager but with different FileSystemOptions.

Addresses rdar://8583824.

Douglas Gregor 15417cfa56 Improve source-location information for CXXConstructExpr nodes, by
ensuring that they cover all of their child nodes. There's still a
clang_getCursor()-related issue with CXXFunctionalCastExprs with
CXXConstructExprs as children (see FIXME in the test case); I'll look
at that separately.

Ted Kremenek d40a439067 Hack to workaround deficiency in ObjC ASTs. Functions and variables may be declared
within an @implementation, but we have no way to record that information in the AST.

Ted Kremenek 818e5c1839 Encapsulate within CXCursor the notion of whether a VarDecl* is the first Decl in a DeclGroup. We use this
to recover some context that is currently not modeled directly in the AST.  Currently VarDecl's cannot
properly determine their source range because they have no context on whether or not they appear in a DeclGroup.
For the meantime, this bandaid suffices in libclang since that is where the correct SourceRange is directly needed.

Douglas Gregor adfdccf1f3 Improve the implementation of libclang's token-annotation logic for
entities in the preprocessing record. Previously, we would only end up
getting the first token of a preprocessing record annotated
correctly. For example, given

  #include "foo.h"

we would only get the '#' annotated as an inclusion directive; the
'include' and '"foo.h"' tokens would be given the general 'processing
directive' annotation.

Now, we get proper annotations for entities in the preprocessing
record.

underlying file to which the inclusion resolved.

full selector name rather than just the first chunk.

Francois Pichet 85e6da1f19 This patch remove the Win32 XFAIL from remap-complete.c

improvements to the compiler and the introduction of crash recovery,
it no longer makes sense to allow this mode. Moreover, this eliminates

all to go away.

Douglas Gregor 9b3932c0bc Fix a marvelous chained AST writing bug, where we end up with the
following amusing sequence:
  - AST writing schedules writing a type X* that it had never seen
  before
  - AST writing starts writing another declaration, ends up
  deserializing X* from a prior AST file. Now we have two type IDs for
  the same type!
  - AST writer tries to write X*. It only has the lower-numbered ID
  from the the prior AST file, so references to the higher-numbered ID
  that was scheduled for writing go off into lalaland.

To fix this, keep the higher-numbered ID so we end up writing the type
twice. Since this issue occurs so rarely, and type records are
generally rather small, I deemed this better than the alternative: to
keep a separate mapping from the higher-numbered IDs to the
lower-numbered IDs, which we would end up having to check whenever we
want to deserialize any type.
