Summary: I could also move `RangedConstraintManager.h` under `include/` if you agree as it seems slightly out of place under `lib/`.

Reapply reverted changes from D46879.
Currently BreakBeforeParameter is set to true everytime message receiver spans multiple lines, e.g.:
```

```
will be formatted:
```
[[object block:^{

llvm-svn: 333154
Summary:
Remove the call to DiagnoseUseOfDecl in LookupMemberExpr because:
1. LookupMemberExpr eagerly lookup both getter and setter, reguardless
if they are used or not. It causes wrong diagnostics if you are only
using getter.
2. LookupMemberExpr only diagnoses getter, but not setter.
3. ObjCPropertyOpBuilder already DiagnoseUseOfDecl when building getter
and setter. Doing it again in LookupMemberExpr causes duplicated
diagnostics.

unusual types.
Following the observed behavior of GCC, we now return -1 for vector types
(along with all of our extensions that GCC doesn't support), and for atomic
types we classify the underlying type.
GCC appears to have changed its classification for function and array arguments
between version 5 and version 6. Previously it would classify them as pointers
in C and as functions or arrays in C++, but from version 6 onwards, it
classifies them as pointers. We now follow the more recent GCC behavior rather
than emulating what I can only assume to be a historical bug in their C++
support for this builtin.
Finally, no version of GCC that I can find has ever used the "method"
classification for C++ pointers to member functions. Instead, GCC classifies
them as record types, presumably reflecting an internal implementation detail,
but whatever the reason we now produce compatible results.

Summary:
Since clang r332929 these two headers throw errors when included from somewhere else than their wrapper header. It seems marking them as textual is the best way to fix the builds.

This matches the Intel documentation which shows them available by importing immintrin.h. x86intrin.h also includes immintrin.h so anyone including x86intrin.h will still get them.
This is different than gcc, but I don't think we were a perfect match there already. I'm unclear what gcc's policy is about how they choose which to add things to.

Summary:
We fail to import a `ClassTemplateDecl` if the "To" context already
contains a definition and then a forward decl. This is because
`localUncachedLookup` does not find the definition. This is not a
lookup error, the parser behaves differently than assumed in the
importer code. A `DeclContext` contains one DenseMap (`LookupPtr`)
which maps names to lists. The list is a special list `StoredDeclsList`
which is optimized to have one element. During building the initial
AST, the parser first adds the definition to the `DeclContext`. Then
during parsing the second declaration (the forward decl) the parser
again calls `DeclContext::addDecl` but that will not add a new element
to the `StoredDeclsList` rarther it simply overwrites the old element
with the most recent one. This patch fixes the error by finding the
definition in the redecl chain. Added tests for the same issue with
`CXXRecordDecl` and with `ClassTemplateSpecializationDecl`. These tests
pass and they pass because in `VisitRecordDecl` and in
`VisitClassTemplateSpecializationDecl` we already use
`D->getDefinition()` after the lookup.

(1) I added some \see cross-references to a few select intrinsics that are related (and have the same or similar semantics).
(2) pmmintrin.h, smmintrin.h, xmmintrin.h have very few minor formatting changes. They make rendering of our intrinsics documentation better.

Previously we negated the whole vector after splatting infinity. But its better to negate the infinity before splatting. This generates IR with the negate already folded with the infinity constant.

more reliably.
Clang has two different ways it emits array constants (from InitListExprs and
from APValues), and both had some ability to emit zeroinitializer, but neither
was able to catch all cases where we could use zeroinitializer reliably. In
particular, emitting from an APValue would fail to notice if all the explicit
array elements happened to be zero. In addition, for large arrays where only an
initial portion has an explicit initializer, we would emit the complete
initializer (which could be huge) rather than emitting only the non-zero
portion. With this change, when the element would have a suffix of more than 8
zero elements, we emit the array constant as a packed struct of its initial
portion followed by a zeroinitializer constant for the trailing zero portion.
In passing, I found a bug where SemaInit would sometimes walk the entire array
when checking an initializer that only covers the first few elements; that's
fixed here to unblock testing of the rest.

The clang builtins have the same semantics as the stdlib functions.
The stdlib functions are defined in section 7.20.6.1 of the C standard with:
"If the result cannot be represented, the behavior is undefined."
That lets us mark the negation with 'nsw' because "sub i32 0, INT_MIN" would
be UB/poison.

These were included in emmintrin.h to match Intel Intrinsics Guide documentation. But this is because icc is capable of emulating them on targets that don't support F16C using library calls. Clang/LLVM doesn't have this emulation support. So it makes more sense to include them in immintrin.h instead.
I've left a comment behind to hopefully deter someone from trying to move them again in the future.

Intel documents the 128-bit versions as being in emmintrin.h and the 256-bit version as being in immintrin.h.
This patch makes a new __emmtrin_f16c.h to hold the 128-bit versions to be included from emmintrin.h. And makes the existing f16cintrin.h contain the 256-bit versions and include it from immintrin.h with an error if its included directly.

Introduced CreateMemTempWithoutCast and CreateTemporaryAllocaWithoutCast to emit alloca
without casting to default addr space.
ActiveFlag is a temporary variable emitted for clean up. It is defined as AllocaInst* type and there is
a cast to AlllocaInst in SetActiveFlag. An alloca casted to generic pointer causes assertion in
SetActiveFlag.
Since there is only load/store of ActiveFlag, it is safe to use the original alloca, therefore use
CreateMemTempWithoutCast is called.
