Michael Gottesman f15c0bb495 Fixed an infinite loop in the block escape in analysis in ObjCARC caused by 2x blocks each assigned a value via a phi-node causing each to depend on the other. 
A test case is provided as well.

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).

Bob Wilson 1b53bc78a3 Fix cross-compiling problems in build-llvm.pl script. <rdar://problem/12986905> 
As with llvm svn r172138, this patch is basically copying some changes that
we've been using for building clang at Apple. Besides cleaning it up to use
xcrun to locate the proper versions of tools, especially for cross compiling,
it fixes the build to work with newer versions of clang that honor SDKROOT
settings in the environment.
