Nico Weber 7769a9044e Formatter: Add a test for bitfields. 
They work fine, but this fifth use of colons (after labels, in ?:,
in initalizer lists in constructors, in objc method expressions, and in
bitfields) wasn't covered by tests yet.

Daniel Jasper 942ee72aff Stronger respect the input codes line breaks wrt. comments. 
clang-format should not change whether or not there is a line break
before a line comment as this strongly influences the percieved binding.

User input: void f(int a,
                   // b is awesome
		   int b);
            void g(int a, // a is awesome
		   int b);
Before:     void f(int a, // b is awesome
                   int b);
            void g(int a, // a is awesome
		   int b);
After:      <unchanged from input>

Daniel Jasper 22cf462234 Format unions like structs and classes. 
Note that I don't know whether we should put {} on a single line in this
case, but it is probably a theoretical issue as in practice such
structs, classes or unions won't be empty.

Before: union A {}
        a;
After:  union A {} a;

Chandler Carruth 953fb087e5 Refactor the x86 CPU name logic in the driver and pass -march and -mcpu 
flag information down from the Clang driver into the Gold linker plugin
for LTO. This allows specifying -march on the linker commandline and
should hopefully have it pass all the way through to the LTO optimizer.

Fixes PR14697.

NAKAMURA Takumi 7ab4fbf5c2 CGBuiltin.cpp: Fix abuse of ArrayRef in EmitOverflowIntrinsic(). 
In ArrayRef<T>(X), X should not be temporary value. It could be rewritten more redundantly;

  llvm::Type *XTy = X->getType();
  ArrayRef<llvm::Type *> Ty(XTy);
  llvm::Value *Callee = CGF.CGM.getIntrinsic(IntrinsicID, Ty);

Since it is safe if both XTy and Ty are temporary value in one statement, it could be shorten;

  llvm::Value *Callee = CGF.CGM.getIntrinsic(IntrinsicID, ArrayRef<llvm::Type*>(X->getType()));

ArrayRef<T> has an implicit constructor to create uni-entry of T;

  llvm::Value *Callee = CGF.CGM.getIntrinsic(IntrinsicID, X->getType());

MSVC-generated clang.exe crashed.

Daniel Jasper 48cb3b97c7 Always put a space after ",". 
I am not aware of a case where that would be wrong. The specific case I
am fixing are function parameters wrapped in parenthesis (e.g. in
macros).

After:  function(a, (b));
