Mixing of AddAvailableValue and GetValueAtEndOfBlock methods of SSAUpdater
leaded to the endless loop generation when the nested loops annotated.
This fixes a bug in the OCL_ML/KNN OpenCV test. The test case is too
complex for FileCheck and would be very fragile.

When small arguments (structures < 8 bytes or "float") are passed in a
stack slot in the ppc64 SVR4 ABI, they must reside in the least
significant part of that slot. On BE, this means that an offset needs
to be added to the stack address of the parameter, but on LE, the least
significant part of the slot has the same address as the slot itself.
This changes the PowerPC back-end ABI code to only add the small
argument stack slot offset for BE. It also adds test cases to verify
the correct behavior on both BE and LE.

Targets can assume that a target streamer is present, so they have to be able
to construct a null streamer in order to set the target streamer in it to.
Fixes a crash when using the null streamer with arm.

Various places in LLVM assume that container size and count are unsigned
and do not use the container size_type. Therefore they break compilation
(or possibly executation) for LP64 systems where size_t is 64 bit while
unsigned is still 32 bit.
If we'll ever that many items in the container size_type could be made
size_t for a specific containers after reviweing its other uses.

only 1/0 result like std::set. Some of the LLVM ADT already return unsigned
count(), while others still return bool count().
In continuation to r197879, this patch modifies DenseMap, DenseSet,
ScopedHashTable, ValueMap:: count() to return size_type instead of bool,
1 instead of true and 0 instead of false.
size_type is typedef-ed locally within each class to size_t.

This patch adds support to recognize patterns such as fadd,fsub,fadd,fsub.../add,sub,add,sub... and
vectorizes them as vector shuffles if they are profitable.
These patterns of vector shuffle can later be converted to instructions such as addsubpd etc on X86.
Thanks to Arnold and Hal for the reviews. http://reviews.llvm.org/D4015

Start extracting helper functions out of -block-freq's `UnsignedFloat`
into `Support/ScaledNumber.h` with the eventual goal of moving and
renaming the class to `ScaledNumber`.
The bike shed about names is still being painted, but I'm going with
this for now.

instructions available as synthetic SDNodes PACKSS and PACKUS that will
select to the correct instruction variants based on the return type.
This allows us to use these rather important instructions when lowering
vector shuffles.
Also moves the relevant instruction definitions to be split out from
the fully generic multiclasses to allow them to match these new SDNodes
in the same way that the UNPCK instructions do.
No functionality should actually be changed here.

We would previously put dllimport variables in switch lookup tables, which
doesn't work because the address cannot be used in a constant initializer.
This is basically the same problem that we have in PR19955.
Putting TLS variables in switch tables also desn't work, because the
address of such a variable is not constant.

Back in r128440 tools/LTO started exporting the disassembler interface. It
was never clear why, but whatever the reason I am pretty sure it doesn't hold
for tools/gold.

This fixes the processing of --plugin-opt=-jump-table-type=arity.
Nice properties:
* We call InitTargetOptionsFromCodeGenFlags once.
* We call parseCodeGenDebugOptions once.
* It works :-)

Also clean up the Mach-O printing of archive membernames in llvm-nm to use
the darwin form of "libx.a(foo.o)".

The tools/lto API is not the best choice for implementing a gold plugin. Among
other issues:
* It is an stable ABI. Old errors stay and we have to be really careful
before adding new features.
* It has to support two fairly different linkers: gold and ld64.
* We end up with a plugin that depends on a shared lib, something quiet
unusual in LLVM land.
* It hides LLVM. For some features in the gold plugin it would be really
nice to be able to just get a Module or a GlobalValue.
This change is intended to be a very direct translation from the C API. It
will just enable other fixes and cleanups.
Tested with a LTO bootstrap on linux.

Previously this led to a circular header dependency, but a recent
change has since removed this dependency, so the correct fix is
to simply include the header rather than forward declare.

for assembly files we can't depend on the offset within the section
after a string since it could be different between producers etc.
Relax these tests accordingly.

it should also add something like LDPO_DYN_NO_PIC to the plugin interface.
