internal nightly testers.  Original commit message:

By popular demand, link up types by name if they are isomorphic and one is an
autorenamed version of the other.   This makes the IR easier to read, because
we don't end up with random renamed versions of the types after LTO'ing a large
app.

Hope I did this correctly :)

make VariadicFunction actually be trivial. Do so, and also make it look
more like your standard trivial functor by making it a struct with no
access specifiers. The unit test is updated to initialize its functors
properly.

SimplifyCFG now predicts some conditional branches to true or false depending on previous branch on same comparison operands.

For example, 

if (a == b) {
    if (a > b) // this is false
    
Fixes some of the issues on <rdar://problem/10554090>

This will be used by SimplifyCfg in a later commit.

I don't think this affects anything but verbose assembly.

"half precision" floating-point with a first-class type.

This patch adds basic IR support (but not codegen support).

pointer or a reference type - we actually just want the size of the
pointer then for that.

The bad sorting caused a misaligned basic block when building 176.vpr in
ARM mode.

Hexatridecimal was added in r139695.

And fix the unittest that now triggers the assert.

This adjustment is already included in the block offsets computed by
BasicBlockInfo, and adjusting again here can cause the pass to loop.

When CreateNewWater splits a basic block, OffsetIsInRange would reject
the new CPE on the next pass because of the too conservative alignment
adjustment. This caused the block to be split again, and so on.

Reenable the tests.

The command line option should be removed, but not until the feature has
gotten a lot of testing. The ARMConstantIslandPass tends to have subtle
bugs that only show up after a while.

bit of style, sorry.

I have no idea why GCC can't cope with the implicit conversion and Clang
can, or whose bug it is. Grr.

variadic-like functions in C++98. See the comments in the header file
for a more detailed description of how these work. We plan to use these
extensively in the AST matching library. This code and idea were
originally authored by Zhanyong Wan. I've condensed it using macros
to reduce repeatition and adjusted it to fit better with LLVM's ADT.

Thanks to both David Blaikie and Doug Gregor for the review!

Don't try to match 'unpackl/h v, v' for 32xi8 and 16xi16 when only AVX1 is supported. Fix 'unpackh v, v' for 256-bit types to understand 128-bit lanes.

No need for an explicit test case for an unsupported combination of options.

properly initializing the target infos. I decided it wasn't worth linking them
in for this, so just switched back to using the Makefile variable for now. We
can reconsider later if we ever get pluggable targets.
