It's possible that the "comment AST" may be replaced or split out in the
midterm, any anyway this makes the headers easier to read.
Developers don't currently need to include "clang-c/Documentation.h" explicitly
and there's no macro to test for availability yet.
The raw comment and brief comment accessors have been kept in Index.h though
brief support may also move here as a separate proposal.
This is not a deprecation, just a gentle separation of concerns as we look to
simplify the built-in representation of comment nodes and support external
comment processors.

Libraries specify enabled/disabled features using macro defs of 0/1, in such cases the -Wconstant-logical-operand

* It is better if we leave third parties to do "independent" benchmark.
* We compare Clang (version unspecified) with gcc 4.0 or 4.2.
* The graphs have not been updated for a while.
* Clang is well known now. I don't think we still need to explain why
Clang is great.

The change was landed without review or test cases.
It trivially broke almost any stable application checking for Severity >=
CXDiagnostic_Error or indeed any other kind of severity comparison upon
encountering a 'remark'.
Mapped to CXDiagnostic_Warning until a workable solution is proposed to the
list that preserves API stability.
(It's also not clear why the rest of r202475 wasn't simply implemented as a
modifier to the existing 'warning' level.)

Prior to this patch, CGRecordLower assumed that virtual bases could not
be placed before the nvsize of an object. This isn't true in Itanium
mode, virtual bases are placed at dsize rather than vnsize and in the
case of zero sized non-virtual bases nvsize can be larger than dsize.
This patch fixes CGRecordLowering to avoid an assert and to clip
bitfields properly in this case. A test case is included.

The __yield intrinsic generates a hint instruction to indicate that the thread
is not performing any useful operations at the moment. This is for
compatibility with MSVC, although, the intrinsic is also part of the ACLE, and
is enabled globally as a result.

We never aka vector types because our attributed syntax for it is less
comprehensible than the typedefs. This leaves the user in the dark when
the typedef isn't named that well.
Example:
v2s v; v4f w;
w = v;
The naming in this cases isn't even that bad, but the error we give is
useless without looking up the actual typedefs.
t.c:6:5: error: assigning to 'v4f' from incompatible type 'v2s'
Now:
t.c:6:5: error: assigning to 'v4f' (vector of 4 'float' values) from
incompatible type 'v2s' (vector of 2 'int' values)
We do this for all diagnostics that print a vector type.

Almost all linkage calculation for VarDecls occured inside of
GetLLVMLinkageVarDefinition except for static data members. Centralize
the logic so that it can be more readily reused.
No functionality change.

It turns out that linkage and visibility have rather similar logic for
both functions and non-variable globals. Split the calculation out so
that both sides may share this code.
No functionality change.

We don't assign counters for implicit Decls, but we were emitting code
to increment the (non-existent) counters and adding empty counter
lists in the output. This fixes the checks in assignRegionCounters and
emitInstrumentationData to do the right thing, and adds an assert for
the pathological case of emitting zero counters.

Expose the enum CX_CXXAccessSpecifier in the python bindings as a property of
the cursor. If access specifier is not applicable to the node, return the
INVALID specifier rather than raising an exception.

after we've already instantiated a definition for the function, pass it to the
ASTConsumer again so that it knows the specialization kind has changed and can
update the function's linkage.
This only matters if we instantiate the definition of the function before we
reach the end of the TU; this can happen in at least three different ways:
C++11 constexpr functions, C++14 deduced return types, and functions
instantiated within modules.

This patch:
1. Adds a definition for two new GCCBuiltins in BuiltinsX86.def:
__builtin_ia32_rdtsc;
__builtin_ia32_rdtscp;
2. Replaces the already existing definition of intrinsic __rdtsc in
ia32intrin.h with a simple call to the new GCC builtin __builtin_ia32_rdtsc.
3. Adds a definition for the new intrinsic __rdtscp in ia32intrin.h

Summary: The condition in the base class is rather strange. It says a target has the 128-bit integer type if the size of a pointer is >= 64-bits. N32 has 32-bit pointers but 64-bit integers. I'm a bit reluctant to change this for all targets so this patch makes the method virtual and overrides it for MIPS64.

Summary:
Correct size_t to be unsigned int and ptrdiff_t to be signed long. The types were the correct size before this change but
the exact type matters for name mangling and exception handling in C++.

A CursorPlatformAvailability can have several "unavailable" attributes, don't
leak all but the first. I'm not sure if there can be several "deprecate"ds too,
but add the same logic there to keep the two code paths looking the same.
