AsmParser: add missed tests

The diagnostics tests were missing from the previous introduction of ifeqs.

[C++11] Pass unique_ptr by value instead of &&.

Suggestion by Richard Smith.

[C++11] Add an iterator_range class template. This is modeled on the
proposed std::iterator_pair which was in committee suggested to move
toward std::iterator_range. There isn't a formal paper yet, but there
seems little disagreement within the committee at this point so it seems
fine to provide our own version in the llvm namespace so we can easily
build range adaptors for the numerous iterators in LLVM's interfaces.

Note that I'm not really comfortable advocating a crazed range-based
migration just yet. The range stuff is still in a great deal of flux in
C++ and the committee hasn't entirely made up its mind (afaict) about
how it will work. So I'm mostly trying to provide the minimal
functionality needed to make writing easy and convenient range adaptors
for range based for loops easy and convenient. ;]

Subsequent patches will use this across the fundamental IR types, where
there are iterator views.

[C++11] Add two range adaptor views to User: operands and
operand_values. The first provides a range view over operand Use
objects, and the second provides a range view over the Value*s being
used by those operands.

The naming is "STL-style" rather than "LLVM-style" because we have
historically named iterator methods STL-style, and range methods seem to
have far more in common with their iterator counterparts than with
"normal" APIs. Feel free to bikeshed on this one if you want, I'm happy
to change these around if people feel strongly.

I've switched code in SROA and LCG to exercise these mostly to ensure
they work correctly -- we don't really have an easy way to unittest this
and they're trivial.

[C++11] MSVC 2012 can't handle list-initialization that calls
a constructor either. Just call the constructor directly. I'll look into
making this work with aggregate initialization some other time (when
I have someone with MSVC 2012 handy to test ideas).

[mips] support FK_Data_2 and FK_Data_8 to fix big-endian debug data

This fixes invalid lengths in .debug_aranges on big-endian mips64
(lengths appear to be left-shifted by 32 bits) and in .debug_loc.

[mips] Prevent %lo relocation being used on MSA loads and stores.

Summary:
Parts of the compiler still believed MSA load/stores have a 16-bit offset when
it is actually 10-bit. Corrected this, and fixed a closely related issue this
uncovered where load/stores with 10-bit and 12-bit offsets (MSA and microMIPS
respectively) could not load/store using offsets from the stack/frame pointer.
They accepted frameindex+offset, but not frameindex by itself.

Don't emit a blank line when running llvm-config --system-libs.

Summary:
Previously llvm-config --system-libs would print something like:

$ llvm-config --system-libs

-lz -ltinfo -lrt -ldl -lm

Now we don't emit blank line. Functionality is unchanged otherwise, in
particular llvm-config --libs --system-libs still emits the LLVM libraries
and the system libraries on different lines.

The current coding standards restrict the use of struct to PODs, but no

C++11: Beware unnecessary copies with auto

It's easy to copy unintentionally when using 'auto', particularly inside
range-based for loops.  Best practise is to use 'const&' unless there's
a good reason not to.

[C++11] Replace LLVM atomics with std::atomic.

With C++11 we finally have a standardized way to specify atomic operations. Use
them to replace the existing custom implemention. Sadly the translation is not
entirely trivial as std::atomic allows more fine-grained control over the
atomicity. I tried to preserve the old semantics as well as possible.
