The new callback, in addition to limiting which keywords to include in
the pool of typo correction candidates, also filters out non-keyword
candidates that don't refer to (template) functions that accept the
number of arguments that are present for the call being recovered.

Fix some review comments.
Add a test for deduction when std::initializer_list isn't available yet.
Fix redundant error messages. This fixes and outstanding FIXME too.

values and non-type template arguments of integral and enumeration types.
This change causes some legal C++98 code to no longer compile in C++11 mode, by
enforcing the C++11 rule that narrowing integral conversions are not permitted
in the final implicit conversion sequence for the above cases.

No new unit tests yet as there is no behavioral change
(except for slightly more specific filtering in
Sema::ActOnStartOfLambdaDefinition). Tests will be added
as the code paths are traced in greater depth to determine
how to improve the results--there are at least one or two
known bugs that require those improvements. This commit
lays the groundwork for those changes.

for it to be used in converted constant expression checking, and fix a couple
of issues:
- Conversion operators implicitly invoked prior to the narrowing conversion
were not being correctly handled when determining whether a constant value
was narrowed.
- For conversions from floating-point to integral types, the diagnostic text
incorrectly always claimed that the source expression was not a constant
expression.

To avoid malloc thrashing give OverloadCandidateSet an inline capacity for conversion sequences.
We use the fact that OverloadCandidates never outlive the OverloadCandidateSet and have a fixed
amount of conversion sequences.
This eliminates the oversized SmallVector from OverloadCandidate shrinking it from 752 to 208 bytes.
On the test case from the "Why is CLANG++ so freaking slow" thread on llvmdev this avoids one gig
of vector reallocation (including memcpy) which translates into 5-10% speedup on Lion/x86_64.
Overload candidate computation is still the biggest malloc contributor when compiling templated
c++ code.

place. Thanks to Chandler for noticing the weirdness in

Basically we have to look into the parent *lexical* DeclContext for friend functions at class scope. That's because calling GetParent() return the namespace or file DeclContext.
This fixes all remaining cases of "Unqualified lookup into dependent bases of class templates" when parsing MFC code with clang.

pointer mismatch. Cases covered are: initialization, assignment, and function
arguments. Additional text will give the extra information about the nature
of the mismatch: different classes for member functions, wrong number of
parameters, different parameter type, different return type, and function
qualifier mismatch.

This is a little bit tricky because during default argument instantiation the CurContext points to a CXXMethodDecl but we can't use the keyword this or have an implicit member call generated.
This fixes 2 errors when parsing MFC code with clang.

them when performing a const conversion on the implicit object argument for a
member operator call on an rvalue.
No change to the testsuite: the test for this change is that the added
assertion does not fire any more.

expressions: expressions which refer to a logical rather
than a physical l-value, where the logical object is
actually accessed via custom getter/setter code.
A subsequent patch will generalize the AST for these
so that arbitrary "implementing" sub-expressions can
be provided.
Right now the only client is ObjC properties, but
this should be generalizable to similar language
features, e.g. Managed C++'s __property methods.

and DefaultFunctionArrayLvalueConversion. To prevent
significant regression for should-this-be-a-call fixits,
and to repair some such regression from the introduction of
bound member placeholders, make those placeholder checks
try to build calls appropriately. Harden the build-a-call
logic while we're at it.
