Chandler Carruth 2603a18769 Fix a crash in SROA. This was reported independently by Takumi and 
David (I think), but I would appreciate folks verifying that this fixes
the big crasher.

I'm still working on a reduced test case, but because this was causing
problems I wanted to get the fix checked in quickly.

More KDP debugging process. We can not set breakpoints, hit them, resume, step and detach while running.

Nick Lewycky 42bca056e0 Don't forget that strcpy and friends return a pointer to the destination, so 
it's not a dead store if that pointer is used. Whoops!

Michael Ilseman 02a6babb3e Unit tests for IntegerDivision. Currently, just a basic sanity check to ensure that the code was generated properly. Future work would be finding some way to test the actual result that would be computed.

declaration to use the same form as in the rest of the file. No functionality
change.

Howard Hinnant 8e747d3671 Apply the emulated nullptr_t with constexpr. This is an unusual configuration that would take advantage of this. But it has popped up in the wild and does no harm to support it.

Sean Callanan 771f1de241 Added a new Xcode build configuration, DebugClang, 
which builds a Debug+Asserts build of Clang and
links LLDB against it.  The Debug configuration
builds Clang with Release+Asserts, for faster
linking and smaller memory footprint when debugging
the build LLDB.

Even out-of-line jump tables can be in the code section, so mark them
as data-regions for those targets which support the directives.

Bob Wilson 4b87768886 Clear UNIVERSAL_SDK_PATH setting when building host tools. <rdar://12360497> 
I also moved the SDKROOT setting into the make flags, since clearing it from
the environment isn't good enough to override a setting on the make command
line.  That hasn't been a problem but it could be, and it's good to be
consistent with the way UNIVERSAL_SDK_PATH is handled.

Sean Callanan 3d654b3044 Brought LLDB top-of-tree into sync with LLVM/Clang 
top-of-tree.  Removed all local patches and llvm.zip.

The intent is that fron now on top-of-tree will
always build against LLVM/Clang top-of-tree, and
that problems building will be resolved as they
occur.  Stable release branches of LLDB can be
constructed as needed and linked to specific release
branches of LLVM/Clang.
