Rename CanFitInto64Bits to alwaysFitsInto64Bits per discussion on IRC.

This makes the behavior clearer concerning literals with the maximum
number of digits. For a 32-bit example, 4,000,000,000 is a valid uint32_t,
but 5,000,000,000 is not, so we'd have to count 10-digit decimal numbers
as "unsafe" (meaning we have to check for overflow when parsing them,
just as we would for numbers with 11 digits or higher). This is the same,
only with 64 bits to play with.

No functionality change.

Teach Type::getAs<TemplateSpecializationType> that a TemplateSpecializationType
for a type alias template can appear as sugar at any level of desugaring, just
like a TypedefType.

Fix the AST representation for non-type template arguments to encode
enough information so we can mangle them correctly in cases involving
dependent parameter types. (This specifically impacts cases involving
null pointers and cases involving parameters of reference type.)
Fix the mangler to use this information instead of trying to scavenge
it out of the parameter declaration.

Fix an edge case of mangling involving the combination of a lambda and typeid.
typeid (and a couple other non-standard places where we can transform an
unevaluated expression into an evaluated expression) is special
because it introduces an an expression evaluation context,
which conflicts with the mechanism to compute the current
lambda mangling context.  PR12123.

I would appreciate if someone would double-check that we get the mangling
correct with this patch.

Add struct keyword before _Unwind_Context.

In the C programming language, we have to add the
"struct" keyword.  Otherwise, the compiler will
emit error message.

Revert r163022, it caused PR13924.

Add a test for PR13924. Do not revert the test added in r163022,
it surprisingly still passes even after reverting the code changes.

Fix two more tests that didn't do anything.

Run test in a freestanding environment so it doesn't accidentally pick up system headers for the wrong target.

While there add a test that verifies that the header parses in C++ mode.

Have ASTUnit::Save() return a bool to indicate save error.

Removes a dependency of ASTUnit to clang-c/Index.h.

[libclang] Remove the ParentKind cursor kind from code-completion results.

This is to reduce dependency to cursors for the code-completion results.

Make our mini-stdint.h platform-independent by using predefined macros.

This also adds a definition for uint64_t, which was causing build failures
on some platforms. (I'm actually surprised this didn't happen on more
builders, but maybe the search paths are different.)
