f4a4bec3a0 ConstantArray::get() (for strings) is going away, use
ConstantDataArray::getString instead.

Many instances of ConstantArray::get() could be moved to 
use more efficient ConstantDataArray methods that avoid a ton
of intermediate Constant*'s for each element (e.g. 
GetConstantArrayFromStringLiteral).  I don't plan on doing this
in the short-term though.

f2bda69cd2 objc-arc: Perform null check on receiver before sending methods which
consume one or more of their arguments. If not done, this will cause a leak
as method will not consume the argument when receiver is null.
In this patch, the null path releases consumed argument.

ffa2c1a48e When emitting an ARC epilogue that looks like a return of 'self',
kill the retain from the return site.

This has the workaround nature.  It's badness all around.

1412816686 Make the __builtin_c[lt]zs builtins target independent.
There is really no reason to have these only available on x86. It's
just __builtin_c[tl]z for shorts.

Modernize the test while at it.

a7a61e2701 Make clz/ctz builtins defined for zero on ARM targets. rdar://10732455
ARM supports clz and ctz directly and both operations have well-defined
results for zero.  There is no disadvantage in performance to using the
defined-at-zero versions of llvm.ctlz/cttz intrinsics.  We're running into
ARM-specific code written with the assumption that __builtin_clz(0) == 32,
even though that value is technically undefined.  The code is failing now
because of llvm optimizations that are taking advantage of the undef
behavior (specifically svn r147255).  There's nothing wrong with that
optimization on x86 where any incorrect assumptions about __builtin_clz(0)
will quickly be exposed.  For ARM, though, optimizations based on that undef
behavior are likely to cause subtle bugs.  Other targets with defined-at-zero
clz/ctz support may want to override the default behavior as well.

"use the new ConstantVector::getSplat method where it makes sense."

Also simplify a bunch of code to use the Builder->getInt32 instead
of doing it the hard and ugly way.  Much more progress could be made
here, but I don't plan to do it.

588d6abf7d The following patch adds __attribute__((no_address_safety_analysis)) which will allow to disable
address safety analysis (such as e.g. AddressSanitizer or SAFECode) for a specific function.

When building with AddressSanitizer, add AddressSafety function attribute to every generated function
except for those that have __attribute__((no_address_safety_analysis)).

With this patch we will be able to
1. disable AddressSanitizer for a particular function
2. disable AddressSanitizer-hostile optimizations (such as some cases of load widening) when AddressSanitizer is on.
