Summary:
Skip the merging of common symbols for ThinLTO modules, they will be
merged by the final native object link. Trying to merge the symbols and
add to a combined module will incorrectly enable the common symbol to be
internalized in the ThinLTO module. Additionally, we will not want to
create a combined module for ThinLTO distributed builds.

This fixes failures in 7 cpu2006 benchmarks from the new LTO API in
ThinLTO mode.

Summary:
This was reversed compared to ThinLTOCodeGenerator for some reason,
and lead to an increased code-size on my tests. I figured that the
weak resolution may internalize a linkonce function, which will be
promoted immediately (and renamed), before being internalized again.

We are poisoning small allocas using store instruction from instrumented code.
For larger allocas we'd like to insert function calls instead of multiple stores.

It does not play well with directories (end up with a bunch of hidden

Also, do not strip the 0 suffix for the first task, especially since
0 can be used by ThinLTO as well now.

Change the ilist traits to use decltype instead of sizeof, and add
HasObsoleteCustomization so that additions to this list don't need to be
added in two places.

I suspect this will now work with MSVC, since the trait tested in
r278991 seems to work.  If for some reason it continues to fail on
Windows I'll follow up by adding back the #ifndef _MSC_VER.

llvm-pdbdump already had code to retrieve column information in the line tables, but it wasn't using it.

Most Microsoft PDBs don't seem to have column info, so this wasn't missed. But Clang includes column info by default (at least for now), and being able to see that is useful for ensuring we get the column info correct.

[LV] Move LoopBodyTraits to a better place, and add comment for simplifying LoopBlocksTraversal. NFC.

Summary: I later (after r278573) found that LoopIterator.h has some overlapping with LoopBodyTraits. It's good to use LoopBodyTraits because a *Traits struct is algorithm independent.

Duncan found that reverse worked on mutable rbegin(), but the has_rbegin
trait didn't work with a const method.  See http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20160815/382890.html
for more details.

Turns out this was already solved in clang with has_getDecl.  Copied that and made it work for rbegin.

This includes the tests Duncan attached to that thread, including the traits test.

Summary:
The eprintf library was added before the general OS X builtins library existed as a place to store one builtin function. Since we have for several years had an actual mandated builtin library for OS X > 10.5, we should just merge eprintf into the main library.

This change will resolve PR28855.

As a follow up I'll also patch compiler-rt to not generate the eprintf library anymore.

This will cause minsize functions to have the same threshold as optsize
