Original message:
If a constant or a function has linkonce_odr linkage and unnamed_addr, mark
hidden. Being linkonce_odr guarantees that it is available in every dso that
needs it. Being a constant/function with unnamed_addr guarantees that the
copies don't have to be merged.

 - This aligns with how existing test suites end up wanting to use the local
   config files, conceptually it makes sense to consider them to be inherited.

Previously, the clang crash handling code would kick in and give a crash
report for these, even though they're not that sort of error.

The reason that I am turning off this optimization is that there is an
additional case where a block can escape that has come up. Specifically, this
occurs when a block is used in a scope outside of its current scope.

This can cause a captured retainable object pointer whose life is preserved by
the objc_retainBlock to be deallocated before the block is invoked.

An example of the code needed to trigger the bug is:

----
\#import <Foundation/Foundation.h>
int main(int argc, const char * argv[]) {
  void (^somethingToDoLater)();

  {
    NSObject *obj = [NSObject new];

    somethingToDoLater = ^{
      [obj self]; // Crashes here
    };
  }

  NSLog(@"test.");

  somethingToDoLater();
  return 0;
}
----

In the next commit, I remove all the dead code that results from this.

Once I put in the fixing commit I will bring back the tests that I deleted in
this commit.

This is another one that doesn't matter much,

place.

1) If the width of vectorization list candidate is bigger than vector reg width, we will break it down to fit the vector reg.
2) We do not vectorize the width which is not power of two.

The performance result shows it will help some spec benchmarks. mesa improved 6.97% and ammp improved 1.54%.

For now this just handles simple comparisons of an ANDed value with zero.
The CC value provides enough information to do any comparison for a
2-bit mask, and some nonzero comparisons with more populated masks,
but that's all future work.

This changes the SelectionDAG nodes from ISD::INTRINSIC_W_CHAIN to
ISD::INTRINSIC_WO_CHAIN which enables easy lowering to equivalent SelectionDAG
nodes (e.g. __builtin_msa_sub_w -> ISD::SUB) in future patches since nodes
such as ISD::SUB do not have a chain.
It also corrects an obvious mistake, namely that the subtract intrinsics were
marked as being commutative.

As per a similar change in r189106
(http://llvm.org/viewvc/llvm-project?rev=189106&view=rev) there isn’t a new
testcase in this patch since the existing tests should test the intrinsics to
the same standard and the best I can do for a testcase would be a fragile
pass/maybe test of whether memory operations can (and do) cross the intrinsic.
