For example, given:
enum __attribute__((deprecated)) T *p;
-ast-print produced:
enum T *p;
The attribute was lost because the enum forward decl was lost.
Another example is the loss of enum forward decls from C++ namespaces
(in MS compatibility mode).
The trouble was that the EnumDecl node was suppressed, as revealed by
-ast-dump. The suppression of the EnumDecl was intentional in
r116122, but I don't understand why. The suppression isn't needed for
the test suite to behave.

We don't need the insertion back into the original vector at the end. The builtin already understands that.
This is different than _mm_sqrt_sd which takes two arguments and we do need to insert.

We had quite a few for different element sizes of integers sometimes with strange target features attached to them.
We only need a single version for each of _m128i, _m256i, and _m512i with the target feature that first introduced those types.

This patch replaces all packed (and scalar without rounding
mode) fused intrinsics with fmadd/fmaddsub variations.
Then fmadd/fmaddsub are lowered to native IR.

Summary:
Please take a close look at this CL. I haven't touched much of
`UnwrappedLineParser` before, so I may have gotten things wrong.
Previously, clang-format would incorrectly format the following:
```
@implementation Foo
- (Class)class {
}
- (void)foo {
}
@end
```
as:
```
@implementation Foo
- (Class)class {
}
- (void)foo {
}
@end
```
The problem is whenever `UnwrappedLineParser::parseStructuralElement()`
sees any of the keywords `class`, `struct`, or `enum`, it calls
`parseRecord()` to parse them as a C/C++ record.
This causes subsequent lines to be parsed incorrectly, which
causes them to be indented incorrectly.
In Objective-C/Objective-C++, these keywords are valid selector
components.
This diff fixes the issue by explicitly handling `+` and `-` lines
inside `@implementation` / `@interface` / `@protocol` blocks
and parsing them as Objective-C methods.
Test Plan: New tests added. Ran tests with:
make -j16 FormatTests && ./tools/clang/unittests/Format/FormatTests

Summary:
Skipping them was clearly not intentional. It's impossible to
guarantee correctness if the bodies are skipped.
Also adds a test case for r327504, now that it does not produce
invalid errors that made the test fail.

These intrinsics are used by MSVC's header files on AArch64 Windows as
well as AArch32, so we should support them for both targets. I've
factored them out of CodeGenFunction::EmitARMBuiltinExpr into separate
functions that EmitAArch64BuiltinExpr can call as well.

Summary:
The previous implementation misses an opportunity to apply NRVO (Named Return Value
Optimization) below. That discourages user to write early return code.
```
struct Foo {};
Foo f(bool b) {
if (b)
return Foo();
Foo oo;
return oo;
}
```
That is, we can/should apply RVO for a local variable if:
* It's directly returned by at least one return statement.
* And, all reachable return statements in its scope returns the variable directly.
While, the previous implementation disables the RVO in a scope if there are multiple return
statements that refers different variables.
On the new algorithm, local variables are in NRVO_Candidate state at first, and a return
statement changes it to NRVO_Disabled for all visible variables but the return statement refers.
Then, at the end of the function AST traversal, NRVO is enabled for variables in NRVO_Candidate
state and refers from at least one return statement.

Mostly this fixes the names of all the 128-bit intrinsics to start with _mm_ instead of _mm128_ as is the convention and what the Intel docs say.

This helps especially when the collision is for a template specialization,
where the template arguments are not available from anywhere else in the
diagnostic, and are likely relevant to the problem.
llvm-svn: 333489
Summary:
This patch adds the newly added `%sub` diagnostic modifier to cleanup repetition in the overload candidate diagnostics.
I think this should be good to go.
@rsmith: Some of the notes now emit `function template` where they only said `function` previously. It seems OK to me, but I would like your sign off on it.

The extra dependencies are added first to the filename vector in
DFGImpl. That clashed with the emission of the phony targets, as
the code assumed that the first index always correspond to the
input file.
