in macro argument pre-expansion mode when skipping a function body
This commit fixes a token caching problem that currently occurs when clang is
skipping a function body (e.g. when looking for a code completion token) and at
the same time caching the tokens for _Pragma when lexing it in macro argument
pre-expansion mode.
When _Pragma is being lexed in macro argument pre-expansion mode, it caches the
tokens so that it can avoid interpreting the pragma immediately (as the macro
argument may not be used in the macro body), and then either backtracks over or
commits these tokens. The problem is that, when we're backtracking/committing in
such a scenario, there's already a previous backtracking position stored in
BacktrackPositions (as we're skipping the function body), and this leads to a
situation where the cached tokens from the pragma (like '(' 'string_literal'
and ')') will remain in the cached tokens array incorrectly even after they're
consumed (in the case of backtracking) or just ignored (in the case when they're
committed). Furthermore, what makes it even worse, is that because of a previous
backtracking position, the logic that deals with when should we call
ExitCachingLexMode in CachingLex no longer works for us in this situation, and
more tokens in the macro argument get cached, to the point where the EOF token
that corresponds to the macro argument EOF is cached. This problem leads to all
sorts of issues in code completion mode, where incorrect errors get presented
and code completion completely fails to produce completion results.

This commit adds context sensitive code completion support for the C++11
keywords that currently don't have completion results.
The following keywords are supported by this patch:
alignas
constexpr
static_assert
noexcept (as a function/method qualifier)
thread_local
The following special identifiers are also supported:
final (as a method qualifier or class qualifier)
override

Use better heuristics to detect if a '{' might be the start of the constructor body
or not. Especially when there is a completion token.
Fix the test 'test/CodeCompletion/ctor-initializer.cpp ' when clang defaults to c++11
The problem was is how we recover invalid code in the ctor-init part as we skip the
function body. In particular, we want to know if a '{' is the begining of the body.
In C++03, we always consider it as the beginng of the body. The problem was that in
C++11, it may be the start of an initializer, so we skip over it, causing further
parse errors later. (It is important that we are able to parse correctly the rest
of the class definition, to know what are the class member, for example)
This commit is improving the heuristics to decide if the '{' is starting a function
body. The rules are the following: If we are not in a template argument, and that the
previous tokens are not an identifier, or a >, then it is much more likely to be the
function body. We verify that further by checking the token after the matching '}'
The commit also fix the behavior when there is a code_completion token in the
ctor-initializers.

- In functions with try { } catch { }, only the try block would be
skipped, not the catch blocks
- The template functions would still be parsed.
- The initializers within a constructor would still be parsed.
- The inline functions within class would still be stored, only to be
discared later.
- Invalid code with try would assert (as in "int foo() try assert_here")
This attempt to do even less while skipping function bodies.

This commit fixes the IdentifierIterator to actually include identifiers
from a PCH or precompiled preamble when there is also a global module
index. This was causing code-completion (outside of C++) and
typo-correction to be missing global identifiers defined in the
PCH/preamble. Typo-correction has been broken since we first started
using the module index, whereas code-completion only started relying on
identifier iterator in r232793.

Currently we return no results when completing inside of the brackets in
a 'char foo[]' declaration. Let the generic expression completion code
handle it instead. We could get fancier here (e.g. filter non-constant
expressions in contexts where VLAs are not allowed), but it's a strict
improvement over the existing version.

attached to a declaration in the completion string.
Since extracting comments isn't free, a new code completion option is
introduced.
A new code completion option that enables including brief comments
into CodeCompletionString should be a, err, code completion option.
But because ASTUnit caches global declarations during parsing before
even completion consumer is created, the option is duplicated as a
translation unit option (in both libclang and ASTUnit, like the option
to cache code completion results).

Adds a new iterator 'data_iterator' to OnDiskHashTable which doesn't try to
reconstruct the external_key from the internal_key, which is useful for traits
that don't store enough information to do that mapping in their key. Also
deletes the 'item_iterator' from OnDiskHashTable as dead code.

Previously we would cut off the source file buffer at the code-completion
point; this impeded code-completion inside C++ inline methods and,
recently, with buffering ObjC methods.
Have the code-completion inserted into the source buffer so that it can
be buffered along with a method body. When we actually hit the code-completion
point the cut-off lexing or parsing.

That bug concerned the well-formedness of code such as (&ovl)(a, b,
c). GCC rejects the code, while EDG accepts it. On further study of the
standard, I see no support for EDG's position: in particular, C++
[over.over] does not list this as a context where we can take the
address of an overloaded function, C++ [over.call.func] does not
reference the address-of operator at any point, and C++ [expr.call]
claims that the function argument in a call is either a function
lvalue or a pointer-to-function; (&ovl) is neither.
